I have a pair of 661 pads that I've been using for a few years. They're good for big impacts, but I have a hard time with them staying put. They're also not super comfy.

Today I had an off and rashed my left forearm pretty badly, bruised some ribs, and the left knee pad slid down during my slide and I took a layer of skin off my kneecap. I'm looking for some better pads that stay put and maybe cover more than the knees. Also a set of pads for the arms.

I saw an ad for a mesh style set in MBA, but I'll be damned if I can find the ad now. Looking around online, I ran across the AlpineStars Paragon pads, which come in arm and knee. The price looks reasonable, but it's hard to tell much else.

Does anyone have a set of these? If so, do they stay put? Are they comfy in hot weather?

If not, what pads to you use?
