I suppose, I might ask how far are you shooting good groups??? If you're shooting good groups out to 40 or so yards, I'd not worry one little tiny bit about a little fletch contact. I really like walk-back tuning, as it tells me more about where I need to go than anything else. But in all honesty, I've got a feeling that isn't the case. As Dan said, you may want to try cock-vane down, and deer if that helps and that is where you'll seem to have the maximum clearance looking at the rest. And like yourself, I bowhunted for several years before I started figuring out what I was doing wrong. Once I started learning, I couldn't believe how SCREWED up a lot of my stuff was. In the last 5 yrs, I've learned far more than I'd had ever known I was missing. I spent MANY years being quite ignorant. The internet is such a wonderful tool for us to learn from, it is quite remarkable.
