Quoted from Optimiser:Regarding the flipper adjustments, I found that if I went 1/8" (3mm) down from stock it made the ball really hard to catch and hold. I ended up in between stock and 1/8". My reference point is to just be able to see the start of the alignment holes at the bottom of the plastic of the actual flipper (not the rubber). I found this the sweet spot for me where I can more easily make the hard shots and can still catch and hold the ball properly.
I like them at a bit less than 1/8" also. I had set them at 1/8" last night, and it feels really weird to be saying this about Houdini but... it made the game too easy (at least with my pitch at about 6.1-6.2). I was averaging 5-7 minutes per ball, which is too long for me. With a little less droop, the shots are makeable but still tight like Houdini is supposed to be.
Some other adjustments I'm liking so far are turning off the extra ball awards for replays and for the bonus multiplier, since it doesn't seem like that would ever be something you'd go for strategically, but setting the extra ball at 2 combo missions instead of 3 since those are fun to shoot for. To me, the most baller shot ever (and that I can actually make sometimes) is milkcan, ramp, scoop when mission #1 is lit, especially with the new code giving you double scoring for hitting the combo cleanly. I've also got the film modes at 60 seconds since some of them seem impossible otherwise, though I keep the stage modes at 45.
