The reason I'm asking is I'm looking to perhaps fletch my own arrows and wondering if the extra expense of a fletching jig with helical capabilities would be a good investment.
If you expect people to tell you, then you should just flip a coin. You're looking for shortcut, and it doesn't exist
Not looking for a shortcut. Looking for advice. Thanks for nothing.
Short answer - yes.
Several of the entry level fletching jigs come with straight and helical clamps - I'd get one with both.
Without knowing your set-up, it's a guess as if it is good - or bad, reality, you are probably going to experiment a bit with both.
I run a 1-2 degree twist in my hunting arrows with Slick Tricks.
They fly good with straight Blazers, but I've found that I like a little spin with the launch.
