The most recent discussion I had was at AIC in Montreal earlier this month. A material mentioned that I had purchased samples of but never really figured out how to use is HDPE board from King plastics. It is basically the material that is used for plastic cutting boards. It is on my list to check out in the near future. Sintra (the real thing not generic substitutions) seems to keep passing Oddy tests along with Komacel (same thing but comes in 3/4" thicknesses). Renshape is still a viable option too as I understand. In other words nothing revolutionary that I have heard of.
