I am thinking of getting a throttle lock for my Silverwing. Has anyone used one on theirs? I have carpel tunnel and my hands get numb and fall asleep. Today it was really painful, and I couldn't even tell I was using the brake. I have seen them on Ebay for $35. I'm also considering getting one of the palm levers, but with the carpel tunnel, most of the stress is having my hand higher and in the same position for a long period of time. Any advice from anyone using them would be helpful. I just need to be able to drop my hand every once in a while to get the blood flowing.
