I have a 45# recurve, I draw 27"'s. FF string what arrow spine in aluminum to start with ,using 125 grain broad heads. Thank you for all replies
1916s should work pretty good, cut to about 28 inches BOP. Try one at that length before you shorten all of them.
1916 or 2016 both should work
I would go with the 1916.
Agree with 1916's, but recommend starting with 29" length. Don't get yourself in the predicament one old arrow tuner found himself in: "I cut it twice and it's still too short!"
