Right mate you are going to make the biggest mistake of your life if you do that. I have owned both mod and stock. Stock: On my 26" i could gap alot bigger and had more power in my moves, but i could not backwheel, switch, sidehop or anything like that because stocks are just to heavy. So i decided to get a mod and i am now riding my beloved zona zip. Mod: On my 20" the weight of the bike is completly different, much easier to flick around and go bigger on, my gapping has downgraded slightly but my sidehopping has gone tremendously bigger and also my backwheeling and also it is alot easier to switch the bike through now (switch: front to back). Tell you mate, i have no regrets going to mod and i tell you now theres no going back to stock thast fro sure. So there you go its your chocie if you want to f**k up your riding career but hey go ahead if you wish. I am just giving out some sensiable and honest advice. Cheers !
