Can someone please tell me what the spine of this aluminum shaft is. Thanks. I couldn't find anything because they do not make them Anymore

I shot them years ago out of a 55# Bear K-mag. They seemed to fly OK, Maybe a little stiff? Cut 29" BOP

My honest guess would be 60#? I guess you could always add point weight to tone them down?

78# spine at 28" bop arrow.

73# spine according to Easton. Now this is one of those situations that shouldn't happen. Like I used 2020 for hunting from my 55# Bear then my 64# ASL Lb.

  If I took a 73# spine carbon, same length, same weight, same point that arrow would fly 2 ft to my left. Guess I don't understand the "spine" thing

Yeap on the 73 lb although on my spine tester they are closer to 75 lb. I've been shooting them for a lot of years from my mid to upper 50's lb recurves and longbows with a 175-200 gr heads
  It's a great heavy 5/16 heavy walled shaft ! Shame Easton chose to drop them

I'm about 99% sure they are .400 spine but that 1% can be a doozy in my memory!

I was shooting them out of 60-65 pound bows drawn 29 inches,shafts cut to 30 inches.That was quite awhile ago.I think they were marketed for 60/65 pound bows on some of the shafts.They came in a few different graphics.Legacy,Classics etc. from what I remember.

Thanks guys 

The Dick Butkus of aluminum shafts .... great knock down power 

They were my first custom made arrows. Got them from the Kittridge Bowhut, about 1973. Shot at a lot of Pheasants with those. Didn't know nothing about arrow weight, arrow drop, just knew those things died just before hitting the bird. Wish I could still pull the weight to shoot them these days, still have a dozen AO.

Looking through some old files, I found a listing of 0.426 for spine a t 28 inches.
