The best shape for a reflexed bow?

(1/14) > >>

Tuomo:
What is the best shape for a reflexed bow? I experimented with the VirtualBow program to search for an answer. Shown here are five different reflexed designs, with a straight bow included for reference. All of the reflexed bows share the following characteristics:

* Length: 66", brace height: 6", draw length: 28"
* Draw weight: 50#
* Identical front profile, optimized for even stress distribution along the limbs.
* Taper rate 0.008
* Three-layer construction; only the core thickness is adjusted to achieve the 50# draw weight
* All reflexed designs have the tips reflexed by 100 mm (4"), measured from the belly side of the handle
* 10 grains per lbs -arrow

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?

Selfbowman:
This is my opinion.

Selfbowman:
That design has broke flight records and won multiple IBO world championships.here is the caul.

Selfbowman:
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.

Selfbowman:
This bow was designed by Alan Case. 64” long. I haven’t shot it in competition but it shot 460 grains 232 yds.
