Would a spine of 75-80 be about right for a 69lb longbow @28. Arrows will be 30" POC's. Thanks, Justin
Depends on the bow, your shooting style, type of string, etc. If it is a Hill style bow, they might be just right. If it is a modern r/d longbow that is cut to center they may be too week at that length. Gotta tune the arrow to the bow.

If it's not cut to center they would be pretty close. Might have to be a tad heavier if your going to put a broadhead on them. Hap
It's a Robertson Mystical.
