Not surprised that the dual bands haven't been passed - too controversial.
10s and 11s will have city wide 'A' band & 'B' band with zonal C band. results will be collected but not published and the brackets are fluid so if you're getting thrashed you can drop down or if you're winning big you can move up.
12s will be as was and nothing else changes AFAIK.
MPL gossip - draw still being fought over with various clubs still debating it. Trips to nelson (number of trips and when) seems to be the common sticking point.
