Total trad newbie, here (haven't even bought my bow, yet....but will, shortly).

I shoot a Bowtech Allegiance at 66lbs.....but I shoot an overspined arrow (I am one to err on the heavy side) for my setup (whitetail hunter). I am shooting a/c/c 3-71's.

What do I need to know to determine which arrows I would need for a 50# longbow......62"......(I don't know what else to ask). My draw length on my compound is 29"...but it's likely 1/2" too long (if the truth be known).

Where would I begin?

Thanks, in advance, for your responses.
