At last someone with some sence!!! these days a lot of players cant afford £80 a time to play, so at least with say 10 players, you can run 2 rows of 5 which of cause cuts costs, or even if you have 7 its all goodIts your choice how many players you have on your roster be it 5, 7, 10 etc etc. We work our prices out based on 7 as that is the Millennium rules but we do not enforce a roster restriction as it makes no real difference to us if you turn up on the day with 5 players or 10.
Hope that helps
