Thanks for the info. I am shooting great with alum. but a little more accuracy and speed sounds great. Right now with a 60# pull and 2413 I need pins for 10 20 30 and 40. I can put most of the arrows in a 6" circle at 40 but the arrow takes forever to get there. A deer could probably leap away before it got hit. I like the ACC but they are wicked expesive.
