We like using objectives over scoring. Or have both a score or an objective.
F-14 -spell tomcat
Bride get to metamorphosis.
Zep pro start tour multiball
Stingray -knock all drops down twice.
Guardians start orb multiball
Just a few ideas. We typically test play and try for 30-40 min for 4 players per hole. Helped make our tournament move quickly.
