Don Stokes< I understand your thinking, sir. But Kev did say he put a blunt on it, not a BH!
I have been playing with hardware, ramin dowels for over 20 years! They are great for training the eye, when it comes to hand tapering, ie nock end, barrel, self nocks, and other fletching techniques!
I have been carrying a couple in the quiver for same period, and have shot a spit load of squirrels, coons and such.
If you fletch a little on the high side, spine is not as critical! I have had some arrows, that "traveled the whole season journey", just fine!
Ramin is almost nonexistent in the stores these days! Popular and birch seem to be the norm.
Have at it, I say! Good shootin!
