I shoot the same 545gr carbon arrows (GT's)out of my 62 and 61# longbow and recurve respectively. I frankly don't trust my own perceptions on the matter of tuning a bow so I get someone very knowledgeable to stand behind me, watch the flight, release, etc. As far as "we" can tell the GT's fly just fine out of either bow. I drop 5gr when I switch from field points to Wensel's but they seem to just zip in straight regardless. All the weight is up front. The longbow is not cut to center but the recurve is. I thought for sure that I would have to change the set-up so I am pleasantly surprised. In fact, I am reluctant to try other weights, arrows etc. because I love the interghangeability of the current set up. I bring both bows on trips and one set of arrows and only have to worry about keeping the strings straight!
