Mostly set them half way, and sometimes fully open if too easy.

Same for me. if i find a game too easy to play i'll set the outlane posts to the widest positions, Kiss is one game of mine that comes to mind where i did this.
After looking at my Stern Galaxy pf last nite, it has 3 positions for the outlane posts, now that game is way too easy imo so its going to get the same
