A wise man's guess would be Stiff Regular flex, between Stiff flex and Regular flex.
The Ping Rapture V2 is probably the most forgiving driver on the market. But the Callaway Diablo wouldn't be far off it.
It is all up to you. You should try out both drivers in various shaft and loft combinations and see which one you like the best. If it was me I would go for the Diablo Edge because it is more recent, so will have better technology and the Nike Sumo 2 is square. Square drivers never really took off.
Callaway make this shaft flex, it is designed in between a regular flex and stiff flex shaft.
It is a Rifle shaft or Rifle Project X, a very very popular shaft, 5.0 plays very close to regular flex.
The intermediate shaft is the shaft going to the driver side wheel from the tranny. The shaft is suppose to eliminate what you call torque steer, It comes straight from the tranny and bolts to the engine block with a bearing race to hold the shaft and at that brace is where the half shaft, or drive shaft connects to the intermediate shaft and to the driver side hub.

there is really no difference except woods are like not as powerful as the driver but the woods can be hit in the fairway not the driver
A Reverse Shaft is the shaft which rotates in the opposite direction of the engine driver shaft with the help of meshing of gears mounted on it to the gears mounted on engine driver shaft when reverse gear is applied. The reverse shaft allows the vehicle to move in reverse direction. Sanjay Singh Rathore (ME 3rd year) M.I.T.Mandsaur
The original Callaway Big Bertha come out in 1991. This club was their answer to the BB. It came out the year after, in 1992. The club measured 44". and the club head volume was 200cc. 10cc larger then the Big Bertha. Available in two different lofts: 9 and 11 degree only. Shaft was made by Aldila and came in two flexes: Regular and Stiff only. Both were low kick points, 3.0 torque and weight was 82grams for the regular flex and 84 grams for the Stiff Flex. Shaft was Dark green which transitioned into silver as it got nearer the Club head. There was also a matching 3, 5 and 7 wood in both regular and stiff shaft. Original cost of the club was $149 with matching Green and White head cover. The MacGregor Reverse Draft Jumbo was their last Steel head driver and was followed by the VIP Titanium Driver. I played with a 9 degree Stiff flex in the Indiana Amateur in 1992. 36 holes in one day and only missed one fairway. Probably my best driving day ever. :)
