I for one do not agree with PK's to determine the winner. If the game is a tie at the end of 2-40 havles and 2-5 minute OT periods, the game should stay as a tie. This tells me that both teams are equal and the game should not be decided based off the keepers abilities...it is a TEAM sport, decided by the play of each team.
I would agree to extending the OT periods to 2-10 minute periods. Seeding based off point system. One last thing, I do favor the Golden-Goal concept for OT. Afterall, both teams had 80 minutes in which to score...
