i wiped my Greenspeed GTS this weekend. We have this 10 mile road course set up on a combination of MUP and golf course cart pavement. it is a total blast on trikes, but it can be quite hairy with off camber turns and decreasing radius turns. the track is perfect for Hare and Hound, or just hammering. my gts only has a 700 mm track (narrower than an aero) so it is not very forgiving, and the scorchers are very sticky. in this roll, i bent a wheel, left an impressive human skid mark and corresponding lack on skin on one arm, and then a cut and softball sized bruise on the other. We were much more conservative on the last 8 miles. the wheel is already back to straight, and the arms are healing nicely.
