We went shoe shopping for my boys tonight at a local sporting goods store and I picked up a pair of fingerless weight lifting gloves. They are all leather and have a padded palm. I rode for an hour tonight and although I still had some numbness every now and then, it was no where near what I had before!
I'm thinking of looking into a throttle lock so I can relieve my right hand without decellerating or having to wait to get to a stop sign.
