"Frankly, I don't see a market for code 100 or 113 molded ballast track."
I don't either. The S "unitrack" is equivalent to what the other popular scales have and can be a stepping stone to flextrack for those who stay in the hobby. All we really need is more product at competitive prices so new comers to the hobby can consider S scale on equal footing to HO or O scales. Being in the sweet spot for size is not being exploited like it could........DaveB
