That is a question of personal preference.

Also, I think you are in the wrong category. Tech is more for mechanical issues with your machine. You might get more responses elsewhere on this forum.

But since you are asking, I prefer to pitch my games higher in the back than the factory recommends. Then again, I am into pinball more as a player than as a collector ... so always like a tougher challenge.

Do you have a lot of beginners playing your machine? If so, you may want to keep to factory standards, so as not to scare them away ... and give them longer ball times.

Do you like your games fast? Then raise those back leg levelers! Just make sure that you test the machine after to make sure that the flippers are powerful enough to make all of the shots!

Hope this helps a little ... and try again on another forum category.

Cheers
