I see my name came up in this thread so I thought I'd respond.
This is just a double dozen bet no matter how you pick the dozens to bet on. Any of the double dozen progressions posted on this forum will give you the same result.
Some DD progressions are aggressive and you have to have a large bankroll to stay with them because you'll be going in the hole pretty deep.
Others are conservative and you won't need as large of a bankroll but you'll find yourself in the hole for very long periods of time.
I always suggest the Penthouse for double dozens. 112233445566778899etc... You move 2 steps to the right on a loss and move 1 step to the left on a win.
Here's some progression lines that go from very aggressive to very conservative. Still 2 to the right on loss and 1 to the left on win.

As a final thought, the 3 step marty is as good as any other progression. A Marty is a very bad idea only if you don't cap it. If you cap it at 3 steps, it's not any worse than other progressions.
If this system wins with any progression, it will win with any progression. Using that logic, it should win with a flat bet as well.
Good Luck to All,
