Quoted from Alaskanzen:Has anyone noticed a difference when changing to a higher pitch. Following feedback where I had heard Keith Elwin recommended a 7% pitch for the game, I bumped mine up from 6.5 ish. I have a small sample size but I've noticed the game seems to flow better and generally play better. Has anyone else noticed a difference in adjusting pitch?
Yes.
Every pin varies with pitch. 6.5 is stern boilerplate. When the designer recommends a particular pitch or other adjustment it means the game plays how they think it should play. Other pitches change the angles and the difficulty to hit or chain different shots can increase or decrease. In extreme cases it can make things like shots that cross the playfield from one guide to another like the crisscross from the shooter to the outer loop not quite line up right.
Best is what you prefer. I keep mine around 6.8/6.9.
Generally:
Shallower = Vertical descent is slower. Horizontal movement is more pronounced or "Floaty." Shots that aren't quite perfect tend to have an easier time scoring instead of bricking, but the extra horizontal movement decreases your own shooting accuracy.
Steeper = Vertical descent is faster. Horizontal movement is less pronounced. Shots tend to need a little more power/accuracy to clear ramps but its also a little easier to shoot with that level precision.
The height of the outlane dividers relative to the highest point on the slings changes and it interacts with pitch considerably. Some are higher, some lower and some dead even to different extremes.
Maiden has one of the lowest if not the lowest of modern sterns. I haven't measured them all but at a glance I suspect all of Elwin's designs are low compared to the average across all modern Sterns. There's an interview with him somewhere long before he worked for Stern where he lambasted what he considered far too easy outlanes. For a clear contrast compare it to a Mando which extends noticeably higher than the sling.
Low divider + Floaty = Brutal because balls that are traveling horizontally just above or rolling over the sling already have the clearance for the divider where a higher divider would have blocked it and are likely to go straight into the wall and down the outlane, upward nudges have to be more forceful to close the distance and balls bobbling at the top of the inlane have a tendency to bounce off the back of the sling tip and roll over where a higher one would hold it in.
