Opinions on alternate mouthpieces material..

[ol bob]

I really like Amodel.

Amodel is a good as you can get, problem is it's almost impossible to get.

So guitarpartsandmore has a PPSU material called Cue Ferrule King which is supposed to be very tough, I have only used it twice so far but it is pretty hard and has an off white color to it, nowhere near as white as the Delrin and a little darker than the Q4. Only downside is that it didn't like my dull carbide cutters and I had to use a spindle gouge instead- if you use carbide and it's sharp it may turn fine...
I like it so far and will continue to use it

I got a piece of ppsu from McMaster Carr and it had more of an off white ivory color in my eyes than Davids ppsu but they both look good. Not to say either could change from batch to batch.  I don't mind the Q4 but the brittleness keeps me from using it.  I had a piece snap in half when I dropped it, same as acrylic mouthpieces sometimes do, and never messed with it again.  It does make a fine mouthpiece just don't ever drop it on a hard surface.

That is a very important concern to me, the brittleness or softness of the mouth piece material because anything can happen when we are hunting.

I have some of the McMaster Carr PPSU but I haven't turned any yet, I'll be checking it out for sure.
That pic I posted was a little on the large side so I resized and fixed it, sorry about that
