I am not getting into the dropaway vs wb debate but I prefer the newer style dropaways that attach to the up cable or the limb such as the limb driver does.
The biggest reason is they provide much more guidance than a traditional style dropaway with less torque on the cables and have no fletching contact.Best of all worlds imo.
I have many reason that (I) do not like the WB.
My rest is the Spot Hogg Whammy and I have only been shooting it about a month but I can tell you it's forgiveness rivals that of my target rest(spring steel),maybe even a little more forgiving.It has tall prongs,which the arrow sits down in,so the arrow will not fall off the rest.It is always up in the ready position,drops right at the fletching and then is right back up again for another shot.It is also a "soft" rest,which means it isn't too rigid,meaning,forgiving.It also has micro adjustments,which I like ALOT.
These things are as important if not more important to a hunter.Forgiveness matters at the moment of truth.Tunability matters when trying to tune broadheads.
I shot a 3-d course with it this weekend and shot a 305(30 target course counting 11's)from the hunter stake.I haven't even been shooting alot this year due to a bad shoulder so let me tell you,I was making a few bad shots but the rest helped.
