What I do now is, draw layouts on pretty much anything. Scan them in, composite in Photoshop. If they're not tight enough, lighten them to around 15% (typically all I need to do is run AutoLevels, then select light Gray as the foreground color and White as the background color, then run Filters>Adjustments>Gradient Map), print it out on regular paper and tighten up the pencils some more. Scan that in, do the Gradient Map trick again and print on Strathmore for inking.
I tried printing in light Blue for a while, but that makes it too obvious what you've done even after inking. The Gray disappears behind the inks so much better. And yes, inkjet printing is erasable, but you shouldn't need to do much erasing at all with this method.
