Quoted from kvan99:The Shadow's ball lock is pretty cool.
Quoted from Cserold:The Shadow ball lock never gets old. My favorite!
Quoted from J85M:Shadow wall lock never gets old still love it as much as the first time I saw it!
Quoted from rplante:I too love the Shadow lock. The way the magnet catches the ball in travel and flings it through the wall is magical.
Quoted from lpeters82:Probably the sanctum lock on The Shadow. I love creative uses of magnets on pinball machines.
I'll cast another vote for The Shadow ball lock.
