Shun the frumious Bandersnatch!
I-blend is a very good Pro plastic. I don't think it's like the 'older' Pro, but a near-Star-quality Pro plastic that is a bit grippier/less slick than Star and seasons in 'not too fast, not too slow'. I've really come to like the I-blend, and Moose is right that it's an ideal plastic for many of the Infinite Discs line of molds.
Okay so more like old Echo Star but not a recycled plastic I would assume. The Innova Star team Touring pros seem get some of that used Star bits in the touring discs should they choose a Star plastic.
