Super League with different format from 7-man???
Don't make the same mistake PSP did, there is only x-ball now(nxl + div. 1,2,3,4...), 10-/5-man are dying.
7-man is next to go if "superpros" play "superleague" and us others stay in the museum... Nobody can relate to these pros if we play a different game.
Keep the 7-man alive and thats the only advantage you have against x-ball. (not that I have anything against x-ball, but if Millenium/NPPL really want to be different)
