I've shot both, but have'nt had the pleasure of letting the air out of one with either. Both have their fair share of fans. I'ts all about sharpness and where you put it. I just tried out some of the new Striker Magnums 1.5" cut heads. No problem with accuracy, but I have'nt tried them any farther than 20 yards. There are so many good heads, just pick one and go with it.
Muzzy, Wasp, G5, Magnus, Barrie/Rocky Mountain, Slick Tricks, NAP, all of them make good stuff. As far as vanes go, or feathers for that matter, the better the state of tune, the less fletching required, but I don't think you could have too much in a hunting situation. I use a variety, 4-fletched 2.5" feathers, 4 and 5" 3 fletch feathers, Blazers, 3" Vanetecs, 4" Flex-Fletch, and even FOBs.
