In other words, the rest wears, and in doing so it is reasonable to believe that the supporting tension and height has changed; and those changes will affect nock height and flight.
Everyone to their own, especially if they are satisfied. However, I just cannot see how supporting a shaft on brush-bristles that wear, break, loose resistance, and " whack" the fletching, can be good.
You shouldn' t be putting " other words" into people' s statements. It completely changes the meaning they were protraying. They used the words they did, for a reason.
I' ve shot the same WB for 2 years now. I' d guess about 25,000 shots have gone through one biscuit. If there is any measureable wear, I can' t detect it. I trimmed the back of the bisquit and cut slots in the bristles, when I first got it. At least 50% of the bristles have been removed since the beginning, and yet it is pretty much just like the day I got it.
I see guys shooting all kind of rests with shrink-wrap covered prongs, and other stuff that wears at least 1000 times faster than a whisker' s bristles. In my opinion the bristles do not wear appreciably and do not readily break or loose resistance. I' ve yet to hear a " whack" on my fletching, and my arrows fly perfectly. Add all this to the obvious benefits of the best " full capture" method being used, and you might see why so many hunters love them. Even if you don' t, it won' t stop me from using one. [8D]
