sounds like 2nd, 3rd would be much better for you. it wont be so twitchy on the pedal control and youll be able to ride a smoother line around the bank. Looks like the wheels keep catching up to the motor/trans so you start to straighten and then have to lift and slow down, then mash again.
no biggie, and it looks like your doing pretty well already. should totally do the Gainesville event when ter-tech throws it
