I agree with Cody (Steel) on what he says about Morrisons and Shrews. I would absolutely get the foam/carbon limbs for the Morrison. I have the first foam core Shrew ever made, and it is fantastic. Unfortunately, I have been waiting on a foam/carbon Shrew for more than a year (I changed my order from the bamboo core bows that I ordered in July 2008 as soon as I got my foam core Shrew at the end of last year). Fortunately, my wait is almost over, and Ron LaClair should be sending the first of my two new Shrews this way in the next few days! I expect from what I have heard from others who have already received their foam/carbon Shrews that they are wonderful. I will post when I get a chance to shoot mine. David Knipes tells me that the Black Swans with foam cores and carbon backing are the best shooting bows he has ever tried. And if David says something, you can take it to the bank!
I know there has been trouble with carbon limbs, and it sounds like Charlie has experienced it, but you will enjoy the foam/carbon bows from Morrison, Shrew and Black Swan, and probably a number of other bowyers. Some exceptional bowyers won't use either material in their bows and they have their reasons. I still buy bamboo core bows without carbon backing from some of those bowyers and don't feel like I am giving up anything because their bows are not designed to shoot with those materials but use the more conventional materials to their best advantage. An example would be something like the new Brackenbury Peerless.
