That would be efficient for a shop, no doubt. For a home mechanic? Naw. I just take a run down to my indy and he exchanges what I've got for what I need. Half the time it's just one out of a whole group. Some of those shim kits are hundreds, although seems to me the hotcams one is like $100 or something. I could see for a guy either way out off the grid, or with a LOT of bikes using the same diameter shims. What other bikes have our size shim?? No need for a pitbull with a center either.
