Thanks DW
I bought the Bohning one because it was a good price... It was a left helical - I really wanted right helical, but the price was so good I figured I could make do with it.
When I got it and found out that it was only the clamp (the picture was the jig & clamp and title said "jig")
The seller apologized and refunded my money - told me to keep the clamp. He also pulled the auction (it was a multiple quantity)
So I ordered the jig and a right hand clamp... then realized I need a straight clamp to repair my kids arrows when they eventually get worn.
So I'd say I'm committed to the Bohning Pro-Clas, for better or for worse at this point.
