i just made the switch to the quik spin vane (glue on vane) and have shot them for about a week and so far im really impressed. a friend of mine uses the quik spins on the shrink wrap that you just dip in hot water, he says they shoot just as good as the glue on quik spins and seem to be just as tough, but he also only shoots for about two weeks before the season so it may not be a fair testimony towards the toughness of the shrink wrap system
hope this helps
