Let's see if I can answer all these questions! If I miss one, let me know and I'll be sure to help you out.

Stat - Yes, there are are fletching jigs out there that will allow for more helical; take a look at the Jo-Jan or the Bitzenburg (sp?). These two jigs take a little longer as you're only able to glue one vane at a time.

Navy - Not only do the wraps allow you to find your arrows easier after the shot (they're bright and stick out more than the surrounding foliage), but they also allow you to see your arrow better in flight. Add to that the fact that blood shows up amazingly well on them and you have a great product!

Kenman - The additional weight doesn't affect your arrow flight one bit. As for cleaning them off, its a lot easier (I think) than cleaning vanes glued directly to the shaft. Heat the wrap/shaft up with either a hair dryer or holding it over a burner on your stove and then simply peel the wrap off, the vanes will come off with it. If there is any glue residue on the shaft, just use a paper towel with a little rubbing alcohol to wipe it off.

MOM - I just use a dull pocket knife to scrape the vanes off. A butter knife (non-serrated of course) will work equally as well. Just use a little pressure and scrape the old vanes and glue off the arrow shaft.

I think I got to everyone. If I missed one of your questions or if another pops into your head feel free to ask.
