I too have acute numbness in both hands that sets in after just a short time period. I have a DP race seat, and it made no difference. Left arm is no problem to dangle and get the numbness out, it is the right - which requires releasing the throttle along with the subsequent slow down, that is problematic. What has made an incredible difference is the TuneBoy cruise control. When on the road droning, set it and you can occasionally dangle your right arm and get some blood into your fingers, and you can do this without the traffic behind you crawling up your rear fender. Too many sprawls down the asphalt at over 100 mph I guess has taken a toll, and now I get to "pay back" for the fun I had racing many years ago. Overall, it still seems like a fair deal.
