hmmn this is a tough one for those who know me you will see that about 5 months ago i wasnt exactly thin... haha however i still managed to do alot of moves that were above the average keeping up with alot of good riders ( not being bigheaded) i soon realised that i was to big basicly and started at the gym along with dieting... i lost alot of weight and gained muscle but i could not do things the way i used to what i was large, so that would fill in the technique part i guess... in my opinion its not about how big your muscle is, its about how fast you can make those muscles move and how you are doing so... i feel that weight would give you a massive agvantage but its not all about that . hope that makes sens haha Paul
