Buy a Muzzy... it' s better.
IF you do go with the Whisker Bisquit... I think you' d do well to do what PAhunter or someone said they did. First thing they did was cut off all the bristles on the back side of the rest away from you. They said there are MORE than you need and by trimming out a layer or two you help save on vanes and reduce the effects of passing through the bristles.
