Last year it was 7man as was the entire NSPL league.
Syd (NSPL Organiser) posted this up a little wile back:
NSPL 2007 - Division Structure
The structure of the NSPL division will change for 2007 in order to cater for more teams needs and ensure that the league is encouraging the development of teams/players from KotH level right up to entering Millenniums.
Div 1 - Locked to 11 Teams
==================
East Coast Irritant
Stealers Am
London Tigers Am
Taunton Snatch A
Bristol Loco
MH2 Llanfair PG
De Novo
South Coast Quake
South Coast Stealers
Outrage UK
Maidenhead Trauma
7-Man, Millennium Ramping format.
Teams not wanting their spot can trade, sell, give it to another team prior to the season starting, but must inform the NSPL of this arrangement. The overal winner of Div 1 2007 will receive a significant money prize equivalent to entrance fee for two Millennium Events in the division of their choice. This must be spent on entering Millennium Events. After much thought, this seems the best prize to be giving out to keep to the NSPL mission statement rather than simply giving out a cheque. The bottom two teams at the end of 2007 will be relegated to division two.
Division 1 teams may play division 1 and 2 teams at SW and SE fixtures.
Div 2 - Unlocked
===========
Existing NSPL teams must discuss moving up to this division with me prior to the start of the 2007 season if they haven't already qualified. They must get my agreement before being granted a place. New teams to the NSPL can choose to enter this division. This division will be locked at the end of 2007 and a significant prize for the winner of the 2008 season and beyond will be introduced.
