I will have to agree with the others on arrows. I've shot many different ones, but recently decided to pick up some ACC 3-60's. Man they shoot great. They are definitely worth the exta money.

I too was using a DZ. It worked great for me, but I wanted to try something with full containment. I picked up a QAD Ultra Rest on Ebay last month. I absolutely love this rest. You can lock the launcer arm into position before you start to draw. For me, I don't seem to worry as much about the arrow falling off during the draw. You can also let down slowley and not have to worry about the arrow falling off. It also has full containment, which is great for tree stand hunting. It seems to be as quiet as the DZ, although I have not done any side by side comparisons. Some have had some fletching contact issues, but if you set it up to lift the launcher the last 1/2" of the draw, you shouldn't have any problems. Good luck on your decision!
