How about multi round Ready go's at different courses? (12 hours per round)
best 5 scores after round 1 win a prize.
best 5 scores after the 2nd round win a prize (not combined just the score for R2)
Then normal payout rules for the overall combined scores.
Shoot awesome in R1 and then poorly in R2 still might get your credits back just for a good 1st round.
