or a 42mm on all screens( this is 4 per deck) or should I mix it up a little; lime decresing the size of appetite as I move away from the feed point.

Over to you guys!!!

if screen is at say....20 deg incline angle......put in 40mm square opening....all 4 screen sections.

at 40mm....sounds kinda like a scalping minus 1 1/2" and down to 0" size.

DEPENDING on the specification gradation 40mm square opg or nominal 1 1/2" SQUARE should be fine. Could go a tad bigger if you desire, 42mm....which would allow for foreshortening of the opening at 20degrees....and this still would work ok.
