I'd want 2 blades for that quiver also, but I shoot a lot of deuces anyway.
The STOS and Grizzly are both very good heads that I shoot a lot. The STOS is a snap to sharpen, both fly like a dream.
I've not had the experiences with STOS TJ has, but I also put a tiny Grizzly tip on mine. STOS has actually started doing that themselves, and gone away from the needle point, but I make mine a little more Grizzly like than they do.
There honestly are very few "bad" heads out there, especially when you're talking trad glue on types, so pick yer poison!
