Thanks. The reason I asked is I have a picture of myself in profile drawing my '67 Grizzly in '69 and I'm drawing the arrow to the back of the point which I am assuming I bought 28" arrows back then. It seemed to me they were the standard and I never even realized they came in other lengths.
Now my draw has shortened in later years and for the life of me I can't figure out why. Maybe shooting heavier weights than I did when I was younger. I know you shrink when you age but was not aware your arms got shorter.
