As you know,the barrel "liner" on carbon barrels is same exact thing as a solid barrel. Unless you're REALLY concerned with weight,I'd go with a top notch solid barrel from lilja,hart,snieder,wather-lothar,etc. Decreased weight and quicker cooldown is the only benefit of the carbon wrapped barrels. Unless you're going to be shooting a lot of rounds quickly,stick with solid. As we all know,temperture is perhaps THE main enemy of barrels,and shooting too quick will heat up any barrel.
