I like the S7 format idea.
In our area we have a hard time finding PSP teams that are willing to go semi and drop the coach. Most of us have seen what happens to players who are too used to ramping when they try to play NPPL.
You see a huge difference in skill level when a player cannot ramp. Roll your markers I say. Leave the machine gun for phenoms and MW2.
I also like the chance to play more than 8 games. This way even if we dont make Sunday we get a good amount of matches for our money.
Just my opinion.
