Well bugger me. Did 60 km on the new PI's last night and they were fantastic. Arse didn't feel like it had done any km's at all. Padding is obviously a lot thicker on them. But they are also a lot more slippery on the seat, which I guess is good because you want to be sliding across the seat, not sliding inside your pants when they grip a bit.
Definitley worth the money (if it weren't for the fact they're selling them for twice what the septics pay for them
).
