I know you said stock but I have had both mod and stock frames: Planet x tibo= Don't go there, doubt you would find one anyway but be glad you can't. Onza T-raptor= A frame that flexes, not my cup of tea. Echo Team 05= Very very nice, very spinny but it got stolen Onza T-pro= Cheap replacement for my beloved echo, very nice geo and a bargain price too. But snapped after a few months. Another Onza T-pro= Just a quick replacement frame for the time being, only cost £40 (A great frame really) Zoo! Python 05 short= Absolutely MINT! Huge gaps and sidehops, was surprisingly spinny aswell for quite a long bike. Gu Typhoon (mod) 07= The SEX! BUY BUY BUY! The stock ones are easier to ride than the mod ones. I absolutely love mine, gaps ridiculously far, loves playing on the front wheel, its like my bestest friend.
