Just some info, I can't really give accurate info, just what I've heard and seen.
my dealer puts the AC float skid under both apex's and nyrto's. There have been others run the stock apex skid, a timbersled setup and another, not sure what. His sled(apex), especially with the PC track went from being cool to rip your arms off. There is one apex with same turbo setup but with the maverick track and timbersled skid and on the same boost 12-14lbs the skinner PC track walks away climbs higher and he says its what gave it the rip your arms off feeling. It appears the setup works awesome on both the apex and Nytro and the way he rides it doesn't appear to have a wheelie problem.
The 2010 pg M8T on 8lbs will out do the other apex(one with maverick track) pretty convincingly. But he is one of the better riders and always makes sure his sleds run at there best.
