Rik, thanks for the explaination of what going on with the shafts. Wheels I have are the Kiekhaefers and they have been back to Merc and are setup pretty good for the application. I understand the wheels I have are a true pitch, vs graduated of the more recent design. Someone up in WI thought that the Kiek. was harder to get on plane but possibly a little better on the big end? I have three pair I was going to try and re-size. One pair would be an easier decision. Maybe it's not feasible to machine them anyway? Thanks again for the info.
