Wondered if you considered making SuperSnap for Standard Gauge.
I doubt it would be a viable business proposition. The market is small, and tooling costs would be substantial. Traditionalists will stick with regular tubular (preferably USA Track and Ross switches rather than the Chinese junk now being imported by MTH) and those who want something more modern or realistic will go with Gargraves or the new MTH Standard Gauge Realtrax. Standard Gauge is a niche market in the first place and I don't see any room for a fourth or fifth track option.
Of course one can't buy what isn't offered, but Realtrax reportedly is selling quite well. And tooling may well exist as Lionel featured a new Standard Gauge track -- made by K-line -- at the NY Toy Fair for the Hiawatha launch. I would choose the pricey Phantom Stainless by Gargraves for a layout. They had a great display at York a few years ago with the Commodore roaring around the booth.
