Honestly, I can't find any reason to not use the WB. Actually I sold my bow that had my drop rest on it, I already had the orginal WB, so all I had to buy to get my new bow shootable, was the new and imporved QS biscuit, not the whole assembly. I also was planning on switching to blazer vanes at the same time, which are great through the WB., so there ya have it. I liked the drop zone, BUT I can't find a fault with the WB. I'm not a competition shooter, which is where I think the drop zone, or other drop rests,would be the best choice.
