I am not a fan of the WB myself, but I know a lot of people use them and love them. I just have a problem with the idea of having my arrow pass thru something like that.
With that being said, I understand why people like the WB for hunting. The full capture of it is nice. There are several drop aways on the market that offer full capture features as well. The QAD is one that a lot people like, I have used one for the past couple of years and have no real compliants.
I am now shooting the Limb Driver and it is by far the easiest most tunable rest I have ever played with, but it does not offer a full capture feature like the QAD or the WB.
