I'll be watching this one. I have always had mixed feelings about using shims.
If the taper between the axle and the hub hold keep it from moving, how does the work with a shim between them? I would think there would be some movement and then only the axle key would be doing the holding?? I don't know.
Axle shims are available from most of the vendors if you go that route.
