Has anyone tried Ergon GP1 grips? I was noticing my hands hurting today and was wondering if the grips would help. They say they help with numbness and palm pain but I'm not really experiencing any of those.

For me its more of a soreness on the outside part of my hand. I only notice it on downhills though, either because on the downhill I'm on the brakes more and straining the outside hand muscles or because on the uphills I'm pulling on the bars a bit more and not putting as much pressure on my hands.

Any ideas?
