That's the question of the day at the moment! No one knows as of yet. There have been some inmates who have bought them, but have not yet put enough miles on them to report back yet. It'll take some time.
I on the other hand, will more than likely be swooping up a set of these in the Spring. They can't be any worse in the mileage dept than a TKC80. And if so, then sweet, the Big Blocks are basically a cheaper TKC80 that gets the same or better mileage.
