Arek, don't let the Southern shandy drinkers wind you up mate!
Had most of the big sportsbikes in the last 12 years, but it's only this year on the 10R that i've scraped the ol sliders.
I'm no Rossi but always been at the front of Inters group or front half of fast group; knee down does not neccesarily mean you are going faster. Tyres and confidence in the bike make a massive difference. Make sure your suspension is set up well and you have good sticky tyres. 209GP's, 211 GP's, Renntecs, Supercorsa's, etc. they will help give you the confidence you need to get it reet ooer in the corners! Rockinham International was where I started scraping, mostly left handers, for some reason I feel better hanging off the left side; this then gave me the confidence to get the both sides down at the next trackday. Keep the faith!
