Where do you guys setup a 3rd crash?

Im a 2 tom guy. 1 up 1 down. I keep a 17 inch crash by my hi hat. 2 splashes on boom arms in the middle my ride very low where the 2nd up tom would be and my 19 inch crash usually over the ride. I recently added a 16 inch crash and have been trying to find the right place for it. I moved the 19 inch crash further to the right and put my new 16 inch crash over the ride. It feels ok idk if im sold yet or i should put the 19 inch crash back where it was and the 16 inch further to the right. Only problem is I'd like to still hit the 16 inch crash on quieter hi hat grooves and moving it further right would make that harder. I don't want to replace the 17 inch crash with the 16 because I feel like the 17 pairs perfect right over my hi hat. Where do you guys usually setup your 3rd crash if you have one?
