Would you recommend this or the race school to help me refine my riding skills in general? I've been riding for 4 years now, been down once, and like to go fast but only when it's (reasonably) safe. I don't want to spend my time learning about watching out for cars in intersections and such, as I try not to ride on busy streets much anyways. I just want to be a better rider, specifically on body positioning and braking. Thanks for the help.
