I was just about to write a nasty gram, when I bumped into the Korkers people at the International Fly Tackle Dealer show. It turns out they were one step ahead of me. To their credit, they realized the durability issue, and will soon come out with "Svelte 2." At first glance, one notices that "son of Svelte" is much thicker, akin to the thickness of the standard felt wading sole. I think the texture also seems a little more coarse, which is a good thing, in my opinion.
