Wondering what size oil lines folks are running for remote filters and oil coolers?

I have AN-12 lines from my pan to my oil pump but I have only AN-10 lines for my remote oil filter. I'm adding an oil cooler in series with the filter so I'll be redoing those lines anyway. Should I stick with -10 or step those up to -12 ?
