I'm with JRW. I wouldn't buy shafts from 3 Rivers or Cabelas either. When I first started out I bought a dozen shafts from 3 Rivers. I "assumed" that they would be reasonably close in weight. Au contrare. They were as much as 70 grains apart. 3 Rivers is a good company and I don't understand why they do that. They could charge a couple bucks more and give you something useable.

I have bought shafts from Raptor and Allegheny Mountain and they give a 10-20 grn range. Other places do the same.
