Me and one of my friends attended the school at Barber and had a blast. I have been riding since I was 14, but have only 3 years experience on sport style motorcycles. I learned more in those few hours, than I have learned my whole time riding and reading books. One of the biggest things I learned was the power of counter steering and relaxing as opposed to unconsciously or consciously muscling the handlebar.
I go to Hallett Motor Racing Circut in Oklahoma often and am pretty slow as I am new to track riding(1 year). I had a huge barrier about entering corners at any speed besides slow. The no brakes drill and quick turning along with great coaching by Jeffro helped me drop 7 seconds off of my time at Hallett, when I went to my next track day 1 week later. I even drug both knees and did not freak out! I still have a lot of learning to do and plan to go back to CSS every chance I get for as long as the wife allows me.
