I'm in year 22 of bowyering but am a little rusty on r/d's.  Osage backed osage.  Two spliced short pieces taken out of rough split timber piece with circular saw.  Light density sage.  63" ntn, 1&3/8"wide.  Tips about even with back at grip unbraced.  Pulling a little over 50# here at 24".     More work on outer limbs?
