Let me first ask you two questions. What is the reason you are debating switching rests. What do you think a drop a way will do better?

And, has your current rest ever failed you in a way that makes you want to switch?

I am not a huge fan of the WB rest, but they do work and are about as simple as you get. And in hunting sometimes simple is best. Drop a ways have a lot of myth surrounding them, don't buy into all of it. Basically the only thing you gain is less fletching contact issues if they are set up properly. They really don't do anything else that any other properly set up rest will not do.

I would say if it ain't broke don't fix it, unless you just like to tinker and spend money.

My opinion anyway.
