Rarely if you are playing golden goal would you have 10-15 minutes. Between the picking of the players, the shots, the long fateful walks back and forth, and the possible sudden death PK's- PK's can easily reach 5 and approach 10 minutes. Granted there will be a few games that won't be decided in those 10-15 minutes, but the cast majority will not be "marathon games." If you must, at least increase the overtime length because two 5's does not give a team much time at all to make something happen.
