It's a great structure, and does allow lots of play , think it has a great balance that gets the tournie moving while still giving lots of play. Although I do admit the jump from 100/200 to 200/400 annoys me in ANY tournie, as its so steep!
Rage against the Machine by Rage Against the Machine, loved it when I first discovered it, and it has never worn off. And I don't normally go for that heavy stuff.
