Dave, Ya there is a physical limit to the slenderness we can get away with, and why I posted that pic since I've had good luck with the stability of these modified ELB styles. I often use a thicker yellow bamboo which helps keep the limb mass low, but does get tricky to keep straight and well worth the effort though...
Barebo, This bow has its own thread about 9-10 pages back. Topics here move so fast that the occasional viewer misses these bows, and I posted it to show basically this. That you can keep it very slender in an ELB style, and use also Ipe as the backing..
Dave's sexy bow, and my example both have a lot of deflex just outside of the grip, and this is basically the key to stability when you get under or very close to an inch in width on these backed bows..
The bow I posted here is with stealthy hunting in mind and I was very happy with how it came out, and why the finish non reflective.. I do make modern shiny styles as too and have a rather wild one I may post soon as well...
On wider limbs I will push the deflex farther out towards the tips since I like this look as well. Speed wise they are all virtually even from what I have seen chrono'd.
I like your "rug" David kinda reminds me of the huge Timber wolf I grew up with. He was a real sweetheart unless you were some dog trying to pick a fight
