HANKFAN, I've been messing with the NAP drop aways since they came out. The 4000 is defifnitely worth the extra, due to ease of tuning. The rest is simple and reliable. I have three of them and shoot alot, with no problems. Installation is easy. Most critical is the lifting cable adjustment. Having not used the other drop aways, I have no comment regarding a comparision.
Hawker, yes the rest drops when you let down. It drops as slowly as you let down, so it is not going to lose the arrow and let it fall off.
Phil.
