I need to try the +8 before deciding. The 22, though much more stable, seems to have less weight transfer to get traction out of the corners, or to shift weight forward to dive in. My local tracks are mostly well groomed and have a lot of tight 180s so the weight transfer seems to help get around the track better. Mental physics says a shorter car will do this better, but the difference in the 22 may be something else, such as the low cg with the big aluminum plate so low in the car.
Definitely interested to check it out though.
