So, which shape is the best? By best, I mean the fastest and the one that stores the most energy. Why? Which design performs the worst, and why?

Does maximim storage energy equate with performance?
I am curious if different designs of the same materiels are more or less efficient when delivering the energy to the arrow.  (what weight arrows are you designing for?)

Max energy storage absolutely does not equal performance. As a matter of fact, a bow could be made to store double its energy and only deliver to the arrow a small fraction of it. I struggles with my short recurve designs stringing energy, so I started focusing on what made them more efficient at delivering that energy. Eventually I got the design sorted out. Think, the energy consumed by the 1950s big engines, but how little they delivered. Same concept.

 I THINK that being said material qualities is huge in design with natural materials but also in general. It will affect the width and length of the limbs depending on the stress from reflex. And yes deflex in the handle and fades takes the stress out and makes the bow more efficient. That being said in flight you need limbs pushed to the max to achieve your goal. Just my opinion. That’s why my bows take more set . If I did it put the reflex In the ends my bows they may not take set. That design has smooth even draw weight and  makes the bow pleasant  to shoot. We all have our design choices though.

Good to see you back.

Here is a bambino backed Osage but I’ve done boo backed boo core and gemsbok horn belly and other combinations this boo backed Osage took some set throughout the limb. It’s best shot with a 462 grain arrow was 260 yds.

This is my opinion.
