Dear Mr. Kidder,

Thanks for reading the article and for your comments. Let me explain to you
the exact process of the Green Line material. It is 95% grenadilla wood
powder mixed together with 5% carbon fibre and epoxy glue. All of this is
pressed under a weight of 80 tons, which is then heated for twenty minutes at
120 degrees Celcius. At that point we have all the qualities of wood. The
density of this material is 1.4 and 1.3 for conventional grenadilla wood. I
consider this material to have the same acoustical qualities as a regual
grenadilla wood clarinet. It is not plastic, but a material with some "life"
in it. There are differences between instruments made of this material with
identical bore measurments and tone holes, the same kind of differences you
would find between two wood clarinets. Several players around the world play
Green Line in major symphony orchestras, and maybe if they are on the list
they could tell you why they play on Green Lines.

I hope this information will answer your questions and please if you have any
other questions feel free to contact me at 847-816-2500 x423. I will be out
of my office from the 11 to the 29 of March. I am going back to the factory
to work with Mr. Lesieux and spend some time in France. I have been living in
the US for a year now and can generally be contacted at any time.

Musically Yours,
Francois Kloc
