Thanks, Steve, for reminding us of this easy experiment we can all try for ourselves — a refreshing break from the “which shaft material is best?” discussions. I have a few questions I guess I’ll have to answer for myself, but maybe you, or another member, already knows.
First, I’d think duct tape would be thick enough that it would tend to curl up on the front edge after enough shots, thus snagging a bit as it passes over the arrow shelf. Cresting tape, which is made to apply to arrows, would provide a cleaner shelf pass-over, but is it thick enough to “turbolate” the air in flight? Even for FoC fanatics like me, I don’t reckon a tiny piece of tape is going to change shaft balance notably. Another fun thing to play with during practice, thanks.
