Go with what feels right for you mentally. In my case, either style of rest will shoot better than the archer behind it. You need confidence in your gear/equipment, if that takes you to the WB vs drop away then you got your answer.
For me, changing up an item or two a year on the bow keeps it fresh and exciting, some guys stick with the same tried and true ever year for confidence, while others tend to get a whole new rig annually. It's what works, feels right and gives you confidence that matters.
