I have shot many of the dropaways mentioned and the rest I use now is by far the best rest I have ever owned. It is the QAD Ultra rest. I have both the LD and HD version and both are great.

The reason I feel this way is this. The rest is a great dropaway and very easy to setup and tune. One of the downfalls of dropaways is that when down they require an arrow holder. Not so with the QAD. It locks in the up position and acts as full containment rest while up. You can let down and the rest stays in the up position. It only drops away on the shot. It combines all the best features of dropaways and full containment rests. IMHO, it is the perfect hunting rest.
