I'm thinking about Perry reflex... Since the bending stresses are distributed internally as well as externally, does that mean you can make a bow shorter?  Like sinewing a shortbow?  How much shorter could a D bow be if it was a laminate?  For example, for a 30" draw, about 64" is likely as short as you'd go for most selfbow woods.  Would you go 60?  58? for a laminate?  Assuming "average" quality wood is used.
