N.A.P Quicktune 3000 micro. It is amazing. You can paper tune the bow VERY easily and that means you have better penetration, arrow flight, arrow speed..... It is a REALLY big performance booster. I think you can get them for around 65 bucks. I am not entirely sure about that though. They are WELL worth the price.

Good Luck This Season: Buck Magnet
P.S. Only Chuck Adams can sit at home and see deer so get into the woods. =;^)
