Ron, you can try mine for comparison next time out - it is a true manual rack. I've never run a de-powered rack so I can't comment on the differences.

I think you just need to man up

I have both. Ran a Powered rack initially, then De-powered it, and then finally swapped in a manual rack. Both the de-powered rack and manual racks were fine on the track at speed. The manual rack is significantly easier in the paddock and at low speed. I also have shoulder problems and have stuck to the manual for that reason.
