That "pin stripping" is called cresting. That is the finishing touch to a dipped arrow. Some people get confused and think that the actual dipping or coloring of the end of the shaft is cresting but it is not. The detailed lines around the shaft whether it is on the bottom or the middle is called "Cresting" If done properly looks great. It sounds like he is an old schoool archer. Good luck with the new arrows. As far as the helical goes, he is right, but also with today's modern drop aways the left - right issue has really become less of a factor. I am a raight handed archer and I shoot RW, just for the simple act that the spin of the arrow actually tightens the broadhead or point upon impact do the the rotation of the shaft. Some archers do like the LW, if they are a RH shooter because it spins away from the bow, It really just comes down to preference. As far as the whole lw is easier to get a hold of, I am not sure but who knows Enjoy those new arrows.
