i have a 27 in draw also and i am currently shooting goldtip xts at 26 1/2 in at about 63 lbs and they fly great. they are 8.2 grns per in. im using 4in vanes(3 fletch) with a 100 grn tip and my foc is about 11.75.now if i shot 3 fletch feathers it would be over 13 so i would have to go with like a 75 grn tip or add a arrow wrap first to get to 8---12.
