To be honest, I think you would be best getting the Di9's because they are a much more forgiving club (they have a larger sweet spot). As to which shaft you should get it all depends how quickly you swing the club. Regular steel would probably be best for you, but graphite will help you get the ball in the air easier, so try that if you have a low flight.
What I would say, is go to your local Golf shop and get custom fit. They can tell you which iron you hit the best, what length you need, which shaft is best for you and if you need a lie or loft adjustment. They will most likely give you this custom fitting service free, and it will dramatically improve your game.
Look at other clubs as well as Wilson, because you may prefer another style.
Young children should really use graphite shafts, they help them get the ball in the air easier and they are a lot lighter than the steel ones. Any clubs I have seen designed specifically for children have graphite shafts. When they get a bit older and stronger say 13-14 they may be able to move on to steel, because their swing speed will have increased and they are a lot stronger. Girls however tend to stay with graphite as they have slower swing speeds and the graphite shafts help get the ball in the air.
Yes, they can. However steel shafts that are long enough to be a driver shaft are very uncommon, this is because they are so heavy and not as good as graphite ones. If you find a steel shaft that you would like put into your driver you will need to check the tip diameters are the same and your local pro or clubmaker should be able to do it for you easily.
You should consult the specific club manufacturers website for full details. You will find that in fairway woods hybrids that the steel shafts are half an inch shorter than the graphite ones, this helps keep the swing weight consistent. So irons do this also, but varies from manufacturer to manufacturer.

It all depends on your swing speed and tempo, graphite is normally for a slower swing speed so you get more flex out of your shafts on the down swing. Go to a golf shop and ask to get your swing critiqued, they should be able to tell you what type of shaft you'll need for your swing. Hope that was helpful In my opinion, use steel for everything except possibly the driver. Steel is a lot cheaper and a lot more durable than graphite, and the advantages of graphite are pretty minimal. Steel shafts are also much more consistently manufactured, so you're more likely to get a consistent variation between adjacent clubs than with graphite. They also twist less under torque than even the best of graphite shafts. This means implies that you will probably get more consistent iron shots with steel than with graphite. Graphite shafts are lighter, so in principle a player should be able to generate a little higher clubhead speed with a graphite shaft. Getting a few extra yards out of your driver might be worth it. Probably not, though. A few extra yards down the fairway would be nice, but I'm more worried about staying IN the fairway. With your irons you don't care so much about maximum distance as accurate, known distance. If you hit every iron five yards further, you now have to hit a soft 8 instead of a normal 9. If you're that good, you probably already have a regular teaching pro, and you would have asked him. Take a specific 360 yard hole. With steel shafts, you hit a 220 yard drive, then a 7 iron to the green. With graphite, you hit a 230 yard drive, then a soft 8 iron to green. Assuming you hit both of them correctly, you're now on the green either way, but you paid an extra $100 for the graphite shafts. After hitting the graphite-shafted 8, are you now so much closer that you are more likely to one putt (or not three putt) than with the steel? Not likely. One possible exception to the above discussion is that graphite absorbs vibration better, so if you have sore hands it is said that it is a little more pleasant to play with graphite. Graphite shafts are manufactured a lot more consistent than you make them out to be. You should most definitely use a graphite shaft in your driver--if they weren't consistent why would Tour Pro's use them? It is also recommended to use them in fairways woods and/or hybrids unless you prefer the feel of steel. Well, NORMALLY if you a man then you get steel and if you a woman then you get graphite. But professionals (like me) get steel. With steel the club comes down harder giving the ball a tremendous power. Some men prefer graphite though because steel is hard to control. The first time I went to steel, i was hitting it horrible but now I'm hitting like a natural, future LPGA pro! Also if you like graphite better, stay with it, it's good to since it gives the ball a good WHIP. Have you seen Pro golfers slow motion back swing with the driver? I'm not sure if you have noticed, but the drivers shaft is amazingly bended which causes the club to make a WHIP which is a powerful thing so the ball can blast out for a hole in one! Graphite is usually 20-30% lighter than steel so you can indeed swing faster with less effort. Yes - cheap graphite has worse tolerance (even shaft wall thickness and even torque (twistiness)) than steel - which is bad. Good quality graphite is beneficial to most beginner to average golfers but lets get the cart before the horse. Most beginner to average golfers would do better to buy high quality steel ((True Temper Dynamic Gold Regular) and spend the money they saved on lessons and range balls.
AnswerYes, unless you're a pro. A hobbyist does not have the swing control necessary to adjust to the difference required for each shaft. The extra flex in a graphite shaft will require a different swing. Playing golf well requires good repetition of proper swings.You want graphite in your woods and perhaps in your Hybrids. Graphite in irons can be spooky as in sometimes the ball will go long and sometimes short. It is more difficult to control the distance with graphite iron shafts. Steel is more predictable.
The Taylormade REAX 55 shaft is a made by Mitsubishi Rayon. The graphite shaft is more brittle and therefore more prone to damage. However, there should be no distinquishable difference in the playing characterics beween the two shafts.
This problem can be caused by a number of issues with your swing. If you are using graphite shafts on your irons, it's clear that you swing with too much power for graphite, and you should switch to steel (which is the "standard" material for iron shafts). For your driver and woods, it sounds as if you're backswing and downswing are violently connected, and it may help to slow your takeaway and use a slight "pause" at the top of your swing. Additionally, most gross swing faults can be solved quickly and easily by your local PGA professional at a local golf club. For an investment of much less than a new graphite shaft, you can get an hour lesson with a PGA-certified pro who should be able to recognize and fix your fault very quickly.
Handicap access
You will be disqualified for handing in a card with the wrong handicap. That is what the rules dictate should happen, if you are given a card with the wrong handicap on it, you should change it.
No you won't. Moreover, your handicap will increase if you practice or play regularly.
If you want a high quality shaft, you should look along the lines of UST, Grafalloy, Aldila or Mitsubishi. I cannot tell you which one you should get because I do not know your game/age/ability etc. The best thing to do is to go get custom fit and try out a few different shafts. Nearly all shafts have different kick points and produce different launch angles. The problem with Callaway clubs though is that shafts go through the head to the bottom of the club, some golf shops may actually shy away from fitting new shafts to these.
