I went from stock to 24 and found the bike alot easier to ride and got me into trials again in a new way, I don't like the idea of mod as I'm 6, 5 and think i'd look rediculous so.. I advise, give it a try, you may well like it, I do taps and sidehops on mine fine, the geo o the zoot is very UCI compared to say, Curtis T24 etc, if you were to buy a second hand one you wouldn't be loosing out on much cash either if you decided to sell on after not liking it... hin hint, BUY MINE. But yeah, its nice if your indecicive or cant get on with either stock or mod..
