Hi, I'm torn on which bike to go for (20"). It's down to either the Yaabaa 499 or onza t-pro. I know there's new onza bikes coming out shortly, but i don't want to run dual disc as i'll be scared if i landed on my rotor. I would like to buy new preferably as i still need to gather money together. What do you think's better, the yaabaa or the t-pro? Thanks, Simon
