IMO the inherent accuracy of a rest is subject to the person using it. Shooting style and form vary from person to person and even the slightest differences can cause specific rests to be more accurate from one shooter to the next. This is where your brace height argument comes into play. Actually, the trick is finding the perfect rest for you. I love the WB and shot it for a while. I then tried a DZ and my accuracy got worse - honest. I went back to a biscuit and was fine. Now I've had a $30 GWS drop-away on since last summer and my accuracy has went through the roof for me. So, the way I see it, the WB can be extremely accurate; for those whose shooting style it compliments; however it is accurate enough for almost all hunters who shoot within their known limits.
