Shouldn't bother it. I've shifted the tiller on my Hills a number of times as I went from shooting split to three under, two under and back and forth. Just changes the nock point on the string a bit. Doesn't seem to affect the overall shooting. I sold one that the guy put a raised rest on, still shot fine once we nocked it right. I can't see that that small a change in the grip would be critical. Personally, I keep everything straight gripped for the last couple of years, just seems more natural.
