Bob Bell/Precision Concepts did my 950 SE suspension, full revalve and I would not recommend them. I heard of his experience with the race bikes and his reputation and spent alot of time and money to get it right afterwards.
For the 950/990 suspension nothing has beat the Superplush bikes I've ridden, both SE and Adventure 950/990. I don't know his secret sauce, but it just works. Give James Sidall a call before you do anything.
