You know, I used to be a WB advocate but I had never tried a fallaway. Once I shot the fallaway on my uncles bow I felt a lot more of a 'lift off' in the bow. When shooting them back to back I feel a slow in the WB. Also, it had been tearing up my vanes, although they are just Bass Pro Vanes. Like I said, though, I really saw a difference in the speed. I also felt that, after getting my rest tuned in, it was quite a bit more consistant.
