Spin versus hammer swag!!! I guess i'm entitled to my opinion too! I've been shooting swaged arrows since 1984 and i've bought them from the"fella in hamilton MT" and from Mikes archery and have owned " spin Swager" for many years now ! I Prefer the spin swage, because I found the hammer swaging too short and it also had a lip at the back of the swage that caused the Broadhead to be difficult to align! if as don aludes to the spin swage looks like a Barbars Pole" Its because the swager head was not hot enough and is twisting the arrow, I can put a perfect 7/8" swage on an arrow with no twist and no strength compromise!!! I make this statement without prejudice, because I only do my own arrows and a couple of good friends for FREE!! MIKE does an AWESOME SWAGING job!
As for Mike G , the answer is that you will lose apprx. 15 grains and it will increase your arrow spine slightly, on the upside it gives you great broadhead alignment. The fewer components to align on an Arrow the fewer problems.
Now im going hunting.
