Problem is the mounting bolts will hit the joystick with their length.
I say a pair of knockoff JLFs from Randy, only problem with round or hexagonal gates is the 4 way functionality.
I'm sure he doesn't want to switch out restriction every time he gets the urge to play PacMan.... but you'd think with all his cabinets 4 way wouldn't be needed on this machine but I'm sure he has his reasons.
Indeed but I would say hex is better than round for 4 way/8way use without a dedicated restrictor (Just my opinion) but I would agree with the JLFs.
The other thing is get one of those above panel 4way/8way restrictor plates but again you may have mounting/astetic issues.
Other than that the only easy switch ones I know of are the Mag stick, J stick and omni 2.
But they all have square restrictors.
I remember seeing one a while ago when I was looking (cant remember the name though) that had built in lever for changing that came through the panel but you would obv have to cut the panel out to allow for the little lever.
Then the servo stick but I wouldnt call them cheap lol
