I'd love to see spec foams. This is my first season running 1/12 13.5 and the cost of buying the variety of different compounds I've used throughout the season is a little obnoxious. I can see how it would deter people from the class. I've had people that seem interested in the class look in my pit box at the 20+ sets of tires I carry around with a confused look, it can't help. I'm sure it's a big reason TC is so much more popular is the spec tire for the stock class.
