I just started fletching my own arrows and wanted to do some testing between different types of vanes to see which shoots best with my setup and was wondering how other people determine this.

Is the best way just to shoot groups at 40-50 yards and see which are the tightest?

Does it matter which type of fletching, offset vs helical, and which brand, blazer vs fusion, you tune your setup for? If I tune for offset blazers should it still be in tune for helical fusions?

Any feedback is appreciated.
