RE: trophy ridge drop zone OR quick tune 4000
I just started working with a Quicktune 4000 and have been pretty pleased with it. It has been very easy to adjust and all the adjustments lock down tightly. I like that the cable is braided steel and not nylon. My only complaint so far is noise. The launcher is a little noisy when drawing an arrow. I think a little fleece will quiet it down nicely. It's a very nice rest.
I have no experience with the Drop Zone.
I have a Trophy Taker Shakey hunter also. It too was easy to set up and is very simple, rugged and extremely quiet. Highly recommended!
