You've only got to look at any race to see a massive difference in riding styles/body positions,so who says what's the "correct" body position?
Look at Bayliss,Doohan & Whitam,all had odd body positions on the bike,but all very fast anyway!! Surely one of the main things is to be comfortable,you always ride with more confidance if you feel good on the bike!! It's no good forcing yourself into a postion that feels awkward,just to look "correct"!! You'll end up going slower!!
