If you are talking about comfortability, a good longboard for rough roads will generally have a good amount of flex to dampen vibrations, some big, soft wheels to absorb shock as well, and some shockpads in between the deck and trucks to absorb more vibration. This type of board will not be great for downhill but that is mostly about skill.
Anything around 62mm or more is good
They can be fun, but regular skateboards are better for tricks and getting some air
No a four wheel drive vehicle will be more ro ugh on the road, it is good for rough roads mainly.
probably the internet. Google search NordBoards that's a really good cheap website with good brands.
Sector 9 sells the cheapest boards, but they are also the known worst brand in the long-boarding community. For a good reliable, and moderately priced board, i'd hit up Lanyatchz Longboards.
There are alot of good companies. You should do some research on www.silverfishlongboarding.com.
for cruising, carving and dancing, yes, top of the line. but speed and sliding isnt really so great.
oh god no, if you want to buy a longboard get a landyachtz, they are in my opinion the best that you could ever buy.
Rubber degrades over the years from exposure to ultraviolet light and oxygen in the air. Rolling on rough roads (and even on fairly even roads) causes wear. A good set of tires is good for about 40,000 miles, but even if never driven, the tires will degrade over time.
a good answer would be He had a really rough week
for starters get the brand called sector nine but if you are experienced get a land yacht board or a loaded board
Bad roads bring good people. Good roads bring bad people. There are exceptions.
