If the Last Crusade saucer is safely catchable from the left and is backhandable, it can be looped for the entire game to get big points.
Shooting Temple of Doom repeatedly is a relatively safe/valuable MB. The 8 ball Ark multiball isn't worth 19 shots.
In competition, only the Temple of Doom shot should be prioritized. Look three, everything is lit for 1 million. Super is the Temple of Doom shot. Super safe and easy too.
Be careful plunging Extra Balls. Don't throw it into the pops if you're one shot away from Last Crusade or you might start the mode.
