I love these, I find the clamping force a bit on the strong side on the 6XX and these pads completely fix that issue. Now I can use them for loooooooong periods without any fatigue.
I have the Elite Hybrid version, I like the plush feel and haven't had any issues with sweating as you might get from cheap materials.
DjangomeisterI loaned them out last summer so I can't say for sure... hopefully I'll remember to check it out if I bother to get them back anytime soon :-p
