RE: recommended cutting diameter on bh's
In a fixed head, my preference is the Slick Trick standard 1'' four blade.
With the 1'' four blade you get 2'' total cut.
A 1 3/16'' three blade makes a little bigger hole, but actually doesn't cut more tissue: 1.78'' total.
The 1'' Slick Tricks fly great from a paper tuned bow.
Either will work, but I prefer the 4 blade.
