this is a rule of thumb for approximating dynamic spine from static spine with hunting weight arrows.

So you don't think it applies because---
willie:
I don't think it is a case of whether it applies or doesn't, I think the rule works better for parallel shafts with a normal range of tip weight, and may be less useful when shafts are tapered and have very minimal tips, minimal fletchings, and you are trying to see how little stiffness (diameter) you can get by with.

I have never used any kind of real approach to flight arrows as I was always primarily interested in the broadhead events. In the week before the shoot I would usually make up about 25 arrows or so according to whatever theory I was trying out and then take them out and shoot them, if they didn't work come back next year with something different. My biggest problem was keeping them round because I taper them on a belt sander turning the m by hand. Best I came up with over the years was a slight taper from front to back with the front 3" tapered and a point more rounded and not needle like. Spine on the better ones was usually a good inch of deflection with 2# weight sometimes even more. The arrow I hit 386 with was about 220 grains if I remember right and purple heart. I never had another good shot with that same arrow but it did consistently hit over 300 yards.

How long was the Purpleheart arrow and what was the point weight? That's fixed for broadhead isn't it?

No I was talking flight arrows with no point weight. I usually spine my broadheads at 55# 28" long about 100 grains point weight. I am having some major issues with the broadhead division right now about fletching and arrows.
