I've got a new bow on order so I've been messing around with Stu's calculator to get me in the ballpark for what arrows might work best. Here's the question: the calculator shows a considerable difference - spine-wise - between using a 50gr insert and a 150gr head, vs. an aluminum insert and a 200gr head. Can just the extra 15 grains from the aluminum insert make that difference, or is it something about having 100 grains right at the end of the shaft with the heavier insert?
(yes, I'm over-analyzing, but that's the way I roll)
