Since my group can't meet that frequently and it's taking about a year per book, I decided to skip DotYK almost entirely (they did a couple of the dream quests) and move the action forward to Okeno, two thirds of the way through WooT. I don't feel like any of us missed that much but by that time only two of the original PCs remained so there wasn't a lot of development wrapped up in the re-acquisition of memories.
