Just wondering if any of you out there could give me a quick overview on how I should go about selecting wood arrows as far as spine, diameter, wood type, etc. I have been shooting Trad Only carbons with either VPA or Steel Force 200-225g broadheads. I understand the process of bare shaft tuning carbons and the spine labeling for them, but it appears wood shafts are labeled on a completely different system (45-50, 55-65, etc). Is this referencing bow poundage or something else? Also, when tuning carbons it was easy to try different tip weights to tweak things, but how can this be done with wood as they need to be glued on? Sorry if these are dumb questions, but I'd like to make the switch and just looking for an overview on the selection/tuning process. Thanks!
