You may be right in regards to your design. Taper rate, limb profile, amount of relex , ect... all pays into it.
In my design I have a more radical reflex and tip wedges stiffened it to much and made it bend more mid limb. With my reflex it worked better without tip wedges and gave a more elliptical bend witch increased the DL capability.
Oh the joys of tweaking a new design!!!!!! Lol
