Hey Chuck,
Where'd da steel force come from???LOL
I have some 140gr glues for sale, but thats another thread.
All my woods and now new carbons I just finished tuning are set with steel force 150 screw-ins ..Great flight so far and as for durability I've spoken to some shooters who use them, and they will not change for anythng. As for blood trails, it's all in the shot amd as for sharpness, a cut on contact with bleeders as I believe yours are to me personally, theres nothing better.
Like anythng else, all personal choice...
