the cen matrix buggy isnt that bad but the truggy is terrible!!! i have a fastory team roller, i olnly have like 2 gallons on the one i have now. i had two. but i dont run it any more, well im running it this weekend because my new buggy wont be here in time. but im selling the Cen buggy or im thinking of making it an electric buggy. dont know yet.
on durability they are both really durable but the wing post break easy, also on the pro kit the carbon fiber towers break extremely easy, i broke a brand new one on the first lap when i over shot a triple, so i had to buy aluminum ones. but other than that the buggy isnt half bad. dont get a truggy though, you will have to spend hundreds just to make it half way decent.
