I haven't previously shot STOS broadheads, but I thought they were out of production and hard to find. If so, I thought I would pass along that The Footed Shaft booth at Kzoo had them in 145g and 160g.
Their web site says "Sold Out"
:dunno:
I know where there is a single pack of 145 grain STOS heads new. I bought 2 packs from John at Twig Archery last week. He had one pack left as of Friday.
