You seem to get the same kids into your shop as I do mine DYI! There are so many ad's out there with "flies identical to field point" or "field point accuracy" it's almost comical. Reality is, most don't. Especially if your bow isn't spot on tuned. ANY tailing whatsoever and that broadhead is picking up air flow and throwing the shot to never never land. No matter what broadhead you are shooting (fixed blade).
Also, glad to see another shop man that points out the realities of the WB rest. Absolutely the stupidest design I think I have ever seen for a compound bow rest! Yet thousands of bowhunters are sucked in to it every year.
