I know that reeds are effected by weather and that wood chanters really require blowing in/warming up to get the best tone from them and that poly chanters are not as good tone wise as wood! SO it comes back to the sound quality and simplicity of use would the carbon chanter give a tone like wood with the easy usage as a poly chanter.

The sound bite I've listened to isn't very helpful as the player is dicking about bending notes as he play's so you don't get a true sample of the chanters sound oh and it's indoors too.
