i have several shafts with graphite in the core and a wood outer layer (mezz hybrid pro 2, cuetec thundebolt, cuetec r360). all are very nice shafts, and I think this is better than a cue made of all graphite. the wood outer core slides a lot better on your bridge and is easier to maintain than graphite. there can be a different sound, but depending on the design, usually it is very little and not a bad thing. it does stiffen up the shaft quite a bit, so you can have long tapers without getting whippy. they are also pretty consistent in terms of radial flex. i assume they are more warp resistant as well, but obviously i have not tried to warp my shaft on purpose to test his
