The Grinders may be tougher or more flat resistant than the Contis, but I haven't had any problems with the Contis so I gave the Grinders away. As always, YMMV.
I noticed in GT's review that he stated the pair he was reviewing was mis-labled as 120 tpi when he knew that they were 60 tpi. I wonder what was going on there and if that was a problem just in pre-production or if some mis-labled ones made it out into the public.
