Alternate shot can be fun among friends.
Someone eluded to what I feel is a good guiding principle if designing "non normal" formats when general attendance/random draw events are concerned.
It's this: There seems to be an unwritten rule that most attenders will want to make 18 drives and 18 putts. Well, …..the putts are negotiable. It's actually more about the drives. And drives with the freedom to make of their own choice (no opposite hand only, rollers/thumbers only, blah) In general, all things being equal, if the unique format takes away a portion of 18 drives, even say a third, some grousing is prone to happen. Of course, This is really magnified if the unique format is sprung upon regular attenders without notice.
That being said, taking a path aside form the normal is a great thing when done right.
Another variation on disc limiting (since this variation is just about disc selection/limits) is the classic "If you only have X discs" theme. One talked about version on a local forum said…
"If you only have 1.5 discs". I guess the op is describing 0.5 disc dubs...
Means: two players - 3 discs total between them. Standard best shot dubs routine.
Utilizes: Negotiation, Compromise, Strategy while not altering the gameplay routine.
