Hello! I' m very new to this board and apologize if I as a question that has been asked a hundred times before. I have a question about rests. First, I have a Hoyt Mt Sport, and I shoot carbon arrows. Currently I have a NAP QT1000 rest.

1. The arrows that I use have helical fletchings and I notice that they rub the launchers on release (the vane developed a black " streak" ). Is the solution to this problem easier than getting a dropaway style rest?

2. The carbon arrow shafts have started to wear away at the shrink tube covering the launchers, and is actually wearing at the aluminum. Do they make a " tougher" shrink tube, or, again, should I get the dropaway?

Thanks!!!!
