I am extremely happy with my LE purchase. Is it "worth" the extra cost? No way. Are the extra feature fun, I think so.
Underworld is fun. I like that it adds a different feed than the up post.
Left ramp diverter is fun to shoot.
Lock is meh. It is less cool than I expected. I don't even really notice that the second ball came from the Canon, it just apprars.
Captive balls are nice. Cyborg multiball is much easier.
Red GI. Swapped it out.
But dialing the LE in has been work, and I am not done yet. Seems finicky. Nothing hard, but finicky to get it working as expected.
