I didn't like surgery recall. It gets a lot of push, but it didn't feel like it was teaching me anything. It depends on your attending's questioning style though. My guy asked management/evaluation and scenario type questions, so a list of 60 factoids didn't really help me much.
Truthfully, I did not really have a true "pocket reference". I had the cards for any progress notes or whatever else and then I'd print off a couple pages of kaplan or a step 2 book for quick reading whenever I got to sat down. My phone got a lot of the random information. I'd also get the list of surgeries for my attending that week and make sure to read up on them with bigger books. I did have one "pocket" book that I can't recall the name of, but the thing was far too big to be in my pocket and I'm 6'5"...
