I too was very skeptable of the wb when they first came out.I had swicthed to a drop away and my groups really tightened up,but there was always the problem of the arrow not staying on the rest which I really had to watch in a hunting situation,and the more I read and talked to others who have tried the wb I decided when I bought my new bow last year I had a wb put on it and I love it and have no problems with vanes coming off.Now i really did love my drop away and one day I might buy a newer model that offers full containment but for now I stickinh with the wb,it's just so darn worry free just get it set right and shoot no moving parts to fail and as far as freezing rain I don't have much too worry too much about that or arrow speed because I'm shooting 272fps with my hunting setup.
