my best results come from financial organization's newsletters.
merrill lynch sends me a ton of this garbage and it works wonderfully.
this paper is moderately heavy but not super glossy which agrees with

but avoid them anyway since its harder to see the pattern and align
it with board
I have had good luck with thinner paper as well but the ML stuff
comes nice and flat for feeding through my copier.
