Thank you for the reply guys.My dealer has the TT shakey hunter,which I'm very interested in,getting the diamondback from cobra,has the NAP quicktune 4000 and another I think,just cant remember which one.
Muzzy---I will be putting it on my Patriot 04 model SC.The TT sounds like it would be a match made in heavin for my bow.
Does the NAP 4000 not have enough adjustment for the center shot?

5 shot-----Whats the "best" most reliable drop away as far as you are concerned.
