What's the chance of making some 20 mm thick palm pucks? That'll make 'em last longer, and it also keeps your fingers up off the road too (assuming you keep the finger pucks 10 mm, or have no finger pucks).
Wear is pretty good. What pucks were you using?? Mine have'nt shown any wear in thickness, bit scratched obviously, and the edges are a little rounded.
20mm pucks could be an option, if there were enough people keen for them. Definitely the point of not having/needing finger pucks would be good... I personally prefer having a slightly thinner puck.
The finger pucks are currently 6mm thick. They are pretty hard to wear down, unless you just slide on your fingers, haha
