Mathews Drenalin Reccomended Arrow Size?
My buddy has a new Drenalin. 29" draw, Muzzy Zero Effect, 26 1/2" arrow length, 70lb draw weight with 100 gr heads..
according to one chart its says 2315's, another says 2213's
His 2315's have terrible porpoising and can't be rid with raising the nock point.. His arrows are all hitting Fletch High in paper...
Any ideas?
