I just started used the online version of Archer's Advantage this year. So far it seems to be close, but I've heard that the spine selector isn't perfect. I'm wanting to try the Valkyrie system on VAP 350s. I'm shooting an 80# Hyperforce at 26.5", arrow cut length is 25" carbon to carbon. If I use an aluminum centerpin sleeve, glue on adapter, and 160 gr Cutthroat, that's ~310 up front. Archer's Advantage is telling me that I will be on the high side of optimum spine with the 350, which is right where I want to be. Is the software fairly reliable, or am I better off with a 300 spine arrow? I've been shooting Zelor 350s cut at 25.5" carbon to carbon, and with 245 gr total up front I'm getting good broadhead flight (with a giant Zwickey 2 blade) with them. Basically I need a way to quantify how much the additional 65 grains up front will affect the spine of the arrow, hopefully before I buy a bunch of sleeves and shafts. Thanks.
