Hmm, an interesting 9 pages of reading. I haven't been following the WB controversy much. The local shop tends to sell 10 of them to any other rests they have in stock and they do not really push it much. I know most of the guys that come in are strictly hunters though so that might have something to do with it. I have set up quite a few of them for folks and do believe they have some obvious benefits which were already mentioned on this thread. I even tried one on my bow a few times but just did not see the need for it because I have not had an arrow fall of the rest yet. (For what it is worth I am still shooting GKF Golden/Platinum premiers and Infinitis on my bows.)
As for Norb, the fact that he uses one does not surprise me. I am assuming this is in reference to his testing and possibly his personal use (if he does hunt). From the testing perspective it makes some sense. Prior to using the WB Ibelieve he would use a standard flipper style rest or a springy style for all of his bow reports. My assumption was that he used it because it was easy to setup and tune with. When doing as many reviews as he does it would only make sense to use a rest that was quick and easy to setup. I would think the same would apply in reference to the WB.
....and I am glad to see that this thread pulled ol' Arthur out of the woodwork.
Just my thoughts.
