The only suggestion I can make is if you're going to keep using the 4" QuikSpins fletch them with a very, very slight offset. The tolerances on the 360* rest are super tight and fletching clearance can be an issue if they're too far offset.
the offset I am shooting is pretty liberal. So this will probably not work for me. But, I will check with the pro shop and we'll check it out for sure. Thanks for the input Justin.
