Several reasons:

It' s very quick to use. I sold my ol' faithful multi-fletcher and bought a Bitz when I switched to tape. Didn' t need 6 arrows drying at the same time any more. And I can fletch a dozen arrows in about a half hour. Quicker if I don' t watch TV at the same time.

I' m kinda a klutz with a tube of glue (I' ve been known to glue my clamps shut [:' (]), and it' s darn hard to make a mess with a piece of tape.

The feathers stay on the shaft until you decide to take them off. I' ve done some serious testing, shooting through stacks of burlap sacks and stuff, trying to MAKE them peel off and they just won' t. I' ve lost arrows and found them a year later after being in 100 degree heat, under rain and snow. The barbs are usually rotted off the quills but the quills are still stuck fast.

When you do decide to take the feathers off, they peel right off. You can scrape the tape residue off with your thumbnail, a wipe down with acetone and you' re ready to refletch. A lot easier than scraping lines of dried up glue off a shaft. So prepping shafts for refletching is a lot quicker and easier.

I always drop a dab of glue at each end of each feather for insurance. But the main thing I' ve learned is to let the freshly fletched arrows sit overnight before using them. The tape seems need an hour or so to cure before the bond gets to it' s maximum strength. I just do my fletching the night before I need the arrows.

Forgot to mention... The tape bonds to every kind of arrow I' ve used it on. Aluminum, carbon - black and camo -, fiberglass and wood (polyurethane, laquer, gasket laquer... It don' t matter what kind of finish is on the wood).
