Jim, funny you quote all my post but the Just MHO line. It seems it has to be a forum of lads patting each others in the back. Am I allowed to desagree, please? I was only talking about MY experience & people I know around me.
The thing I most dislike about new materials is that they're suposedly 'enviromental friendly'. That's b*ll*cks to me. Indeed, instrument makers make the most of the materials they use. Furniture and paper industry are a lot more damaging for forests. So, the label 'enviromental friendly' is a highly hypocritical thing to me.
And sorry, I wouldn't touch one of those plastic fiddles even with a blarge pole.
Cheers,
Fer
PS: Coming back to the begining of the thread, I think that approach to build concertinas is to try to re-invent the wheel. The point is, if something works fine, why to change it?
