IMN,

I have to disagree for the most part. Though I do agree that on some setups there can be a compromise of tune (an average as you say) to get both fp's and bh's to impact the same, I think the change in spinebetween the two has a very, very, small role in it. In fact I don't think the longer bh head really effects spine at all. If anything it has a very small effect on FOC, such a small effect that IMO makes no diff at hunting distances. Using field points I can add 25 grns to tip or lengthen my arrow by 1" and see no percievable group tune diff within hunting distances. Carbons have a very broad spine range. It is all in the blades of the fixed head.

I have not come across a set up yet - under 300 fps that I could not get impact closer than 5 to 7 or more inches off at hunting dist(less than 30). Or ever moved group dist of that size closer, with the effect of opening up the group tune of a bh.

I do agree that when talking about an inch or two group diff., with both acheiving very good groups, that bow can be in the best tune for its bh's and to move the groups to get the same impact may indeed be a compromise.

But once you are that close, why not give it a little tweak and try to get them to impact the same. I doupt you will see any diff in your bh group tune, and it will make practicing much easier.
