The Good: Lightweight No knurling to get drit stuck in Grippy Affordable
The Bad: I think I may have slightly bent a spindle as I feel something uneven when I pedal with these Shinners if you are worried about them, but they happen less then with plastics.
My local bike shop owner even rides these and you should see his bike. He runs top of the line everything. I prefer more grip because I hate slipping off pedals. I am hating my Twisted PCs and slip off them so often so I get a lot of shinners and bruises. Shit ends up causing more pain then metals. I run Odsy JCPC right now and I like having grip much better. I had one slip on them and it barely even hurt.
