ORIGINAL: BarryReade I would try a 9X6.5 or a 9X7 depending on the wind and let the motor scream. You won't be able to pull the pylons as hard with the 9X7 but the extra speed might be worth it. It would be like taking the high line around the track at a NASCARSuper Speedway.
Anyway Dave, you will have fun.
As I said before 9X6.5 or 9X7
