I talked at great length with Dave at the Kalamazoo show about his bows. Disregarding any of the arguments about carbon verses glass he is now using carbon out of shear necessity, as the woven pliable fiber glass that he has used in the past on the back is no longer in production and his supply is depleted, he is now using the flexible woven carbon. Understand that the backing on the back has to flex over the raised nodes on the back. The current production glass is not flexible enough and it's strains only run longitudinally so it will separate along those longitudinally strains if bent to the degree when applied over raised nodes, where as the older out of production woven glass is not only flexible it is woven so it would not separate. Thus the new carbon will add one added improvement and that is longitudinal stability.
If you want to argue about the use of carbon maybe you should talk with Howard about why he started using glass on the backs of his bows in the first place. If you want a longbow constructed using concave, convex shaped Bamboo laminations you are going to have to settle for either NO glass like Howard's pre-glass bows or Carbon on the back.
Now having said that I am sure that if you can come up with some of the out of production woven glass Dave would be more that happy to use it.
Please understand there are lots of great bowyers out there making lots of great longbows, but the MAIN REASON that anyone buys a Dave Miller longbow is, that as far as I know, he is the only one constructing the longbows the same way that Howard did.
I do not mean to upset anyone with this post, nor is it aimed at anyone but we can all debate issues or changes in building materials or designs and for sure that is good but to a degree, please lets not nit pick. Sometimes it is not more important to post questions, thoughts, facts, and insights rather that opinions.
One last thought adding carbon it is not exactly like adding TRAINING WHEELS.
