Talking about the pad, I was looking at P33 Plastazote 20mm thick foam and that weight would be pretty much the same as the GG pad. I was thinking that I could get 25mm pad and cut it to fit the pad sleeve to see if that'd be any stiffer than the original pad. Anyone has any experience of 10mm, 20mm, 25mm, 30mm etc P33 foams and their stiffness? How was it working with it? Does it bend easily or is it stiffer a bit like styrofoam?
