the bow i am currently building, 64in. med r/d with a 20.5in riser came out 50# @ 28in. that is without any sanding on the glass or rounding of the edges so after finishing i know from experience that i will loose a little more and i really dont want a bow under 50# so i was thinking i could reduce the length to 62in. what i would like is some input if it would work and how much # i could possibly gain HELP APPRECIATED!
