This topic seems to get debated every year or so. Last year I was firmly on the side of the WB. I use one on my current setup. It worked great . . . for a while. After putting many shots through it, I started to see wear on my vanes. At first I thought I had a case of a bad glue job. I took my arrows in and had them reglued. Well, sure enough, my vanes starting peeling away from the shaft again. I started dabbing the tip of the vane with superglue. That wouldn't hold it. the WB ate me up.
I shot excellent groups with the WB, but IMO it ain't worth the hassle.
I'll have a TT shakey hunter or something similar after this seasons javelina and deer hunts are over.
