We always play with 5 minute perioids, penaltieson, line changes on, manual goalie, when playing head-to-head.
Sometimes we play Two-teammates, penalties off,linechanges off, manual goalie, 10 minute perioids. We scored 51 goals with Chicago against Ottawa playing with those rules. We're still waiting for Evan to put those sreenshots on nhl94.com .
I think linechanges are a must when playin' head to head. And I recommend you try playing with those rules with Tampa Bay vs San Jose. It's a classic. Played about 200 games with my friend with those teams.
