I did attend my first Rev clinic with John just last month. I will say that it was a worthy investment and my flying (since I am brand new to quad line) is off on the right foot. I was worried that being a new flyer, that I would be left out or forgotten. Not so - John took every student at their own level and everyone improved by the end. I want more and plan to attend more clinics next year! Hoping the schedule is published soon as time off from work is getting harder to schedule on short notice :-)
