Does it really matter?
Get the type of frame that suits the way you ride??
If you wanna be doing the more fun, street style (bmxy) type of riding, then get a short frame, and do it.
If you wanna be doing the not-so-fun hop hop style riding, get a long frame and do it!
It's all trials at the end of the day!

PS.. I prefer the first option.. So I ride a zebdi!
Leon is an AMAZING fast, smooth rider who can go VERY big.. on his SHORT frame..
Nick is also an AMAZING rider, who can go very big.. on his LONG frame!
ah f**k it, just ride and have fun with your mates.. thats wat being a trials rider is about?
