Results: The fletched arrows and the bare shafts grouped within a 5" circle around the bullseye at 20 yards and 75% were within a 3.5". There was no discernible difference or pattern that I observed with the fletched or bare shafts. For a while there I was thinking the bare shafts were actually flying better but I might just have been impressed with how they flew so well.
So, what does this tell us? I don't know. What happens if I put cap wraps on like I want to with the next batch? I think I'm close, just not sure I'm quite there.
I don't think I'd do much with it at this point. Unless you know you can shoot way better than that, it sounds like your spine is not an issue. Are you shooting with the bow vertical? If not, you can sometimes misread a nock point problem as a spine problem. If you are still getting the wag with a vertical bow, it could be spine or it could be string torque. There are a number of variables at work when you release an arrow. Spine is just one of them. Cap wraps may stiffen your arrows a bit. You may want to experiment with the tip weight with your wraps vs without.
In my experience, Woodsman broadheads don't fly enough different from field points to work for tuning. A wide two blade would be better for tuning. If the wide blade groups with the field points, the Woodsman will too.
Carbon arrows are kind of funky to tune, for me anyway. They seem to be extremely sensitive to length, leading to plenty of frustration on my part. If you want to be 29.5", I'd bet 250's are going to be too stiff for your setup. I'd have to load up the front-end pretty heavy, which is not necessarily bad but can lead to heavier overall weight than you may want. I like heavy arrows, so I don't mind.
Good luck. Tuning in the off season is kind of fun anyway.
