I here ya loud and clear, Steve! But I can't see Russia from my house!
I recall reading how Howard would shoot others arrows, short, long, underspined, with accuracy! Fred said he would rather shoot 100 grains difference, but did like close spine weight.
I saw my friend, Gary Davis, shoot the Big Bear at Cloverdale, many years over, with his selfbow, and others arrows, or their bows, with his or their arrow, with great accuracy!
I'm guilty as charged, I carry and shoot various arrows from my quiver! I'm still having fun!
