When printing fairly thin booklets that will be displayed in plastic racks one issue is that after a while they tend to droop down in the racks. Would the grain direction help with this? For a 9x12 finished size booklet printed on 12x18 and folder, would you print on 12x18 or 18x12 stock? Would you ever mix the two to obtain a stiffer booklet in both directions?

You'd want 18x12 if the finished book sits 9x12 with the 12" vertical. 12x18 if the 9" sits vertical. You can also shrinkwrap with a cardboard backer to help the droop if cost effective. Or try to display them on less of a angle if possible. What type of booklets?
