I thought of a variation on best shot doubles but have yet to try it out.
When we play in a best shot dbls league there are often lots of teams and there are often lots of ties for the cashing spots. The ties may split or play sudden death or even do a CTP, depending on the league and the preference of the tying teams.
My variation only acts as the first tie breaker: the team with the MOST WORST DRIVES used wins the tie.
Both players on the team drive. The team can choose either drive but the team keeps track of how many times it chooses to use the worst of the two drives (as determined by the opponents on the card). So if two team tie with 10 under (for example) but one team used 6 worst drives and the other only used 1 worst drive the team using the 6 worst drives wins.
This tiebreaker rewards multiple good drives and sometimes the courage to choose and make the harder putt.
In terms of strategy any time a team has two pretty equal drives they should play the worst of the two (the opponents MUST designate a worst drive even if one is just barely worse than the other). It is common to have two decent drives, neither of which is likely to be birdied but either of which is likely to be parred. On an easy hole it is common to have two park jobs, either of which will cash a birdie. But if one drive is parked and the other leaves a 30 foot putt, now the choice is tougher. A doubles team should hit a 30 foot putt with two tries but it is risky to give up the sure thing.
A team is never required to choose a worst drive (it is best shot, after all) so any team can just play the traditional game (and hope nobody ties them).
As an aside to this discussion it is common in the leagues I play for some teams to play much slower than others. I play fast and usually my group is one of the first ones done (unless we get stuck behind slow groups or casuals). Sometimes I wait around for a half hour or even an hour for the last stragglers to finish. If I sit around for a while my old, decrepit body stiffens up (like temporary rigor mortis

). By the time all the cards are in and a CTP is declared I have no chance of throwing a good shot.
Today my team finished in a 3 way tie for a cashing spot. When the other teams rejected a split, my team rejected a CTP and insisted on a sudden death playoff. I knew I wouldn't be much help on the first playoff hole but hoped I could help thereafter if we were still alive.
As a 2nd aside, there is no way a TD or League Director can prevent players or teams from splitting. Some TD's try to ban it but no one can stop private agreements so it is a waste of time.
