Not to derail the thread from its original intent. But, in response to sailordad's post:
I've struggled with the accepted "definitions" and criteria that determines what an ELB is. Let's assume that a particular bow meets all the criteria for an ELB except one, and that being the one you commented on (that the bow must be at least "man tall"). Let's assume said bow is 72 inches in length. This bow would be an ELB in the hands of a 70" tall archer but would no longer be an ELB in the hands of a 76" archer. The bow didn't change, but its classification did. Seems ridiculous to me to measure something with a standard that isn't fixed. You can argue til you're blue in the face about what makes an bow an ELB, but it's futile.
GPW: backed ERC are snappy shooters, aren't they? I, too, like them 70-72 inches tall and D shape in cross section. The design is very forgiving shooting inaccuracies and look (and smell) great.
Now to the original post: I agree that the pyramid is a fantastically efficient, sweet drawing, easy to tiller, high-cast-potential design that works well given the right wood. Yet I agree with Jawge in that you can't always get the bow you want out of a piece of wood due to its specific gravity, width, length, crown, etc. Nonetheless, I've made many pyramid bows and teach bow building classes where students build a pyramid board bow in a day. The design is not only a great teaching tool, it produces a respectable weapon.
