I tried them a few years ago. They do run small I put the M60 on a 0.600 shaft which should give you a standard size and they were undersize (-1/32" if memory serves) so the walls are thinner on them. Probably cos they are aimed at the Japanese sizings. They were ok but not the best when wet and if you go for a light colour be prepared for them to look dirty after a couple of rounds I couldnt get them cleaned up.
