I agree that they are accurate if you are a statue, but most of us are not. A machine can shoot a perfect 30x on Vegas targets with a Black Mamba X1 just as easily as with a black ice. It doesn't matter if you put a drop away or WB on that thing will shoot it the same every time. It's more about form. Drop aways just make it easier for the average shooter that moves a little bit where as the WB will show every bit of it.

I am absolutely shocked that you are shooting feathers through a WB. I tried it for the heck of it because someone told me that the WB would rip them right off. Ten shots later, that arrow had nothing left but glue. I shoot feather because they are lighter than vanes, but would never seriously put them though a WB.

IMO, a drop away is an upgrade because I shoot better scores with it than with a WB.
