I have a couple of Schon R series with their original tips on their perspective shafts. The closest thing to emulate these tips IMO are Triangle tips. Does anyone know what tips Bob "originally" installed when he was with Schon back in the 80's per chance? I only know they weren't layered tips. I'd like to buy a couple of these tips if these tips still exist. So... for starters what are they and who's got them?
