after a few times going in and out of the sim, this would be my advice. study hard over the flows and profiles that you dont' regularlly see, even brush up on the ones you do, as you may have changed some things flying the line, and doing it to the book standards will make it a little easier for your interaction with the check-airmen (remember, these guys rarely fly the line....most would be freaking out if they did). Besides that stuff, there's not a whole lot of good ways (i know of) to keep up on all the unusual sim stuff you do, besides chair flying it. Try your best to be really easy on the controls, remember the sim only takes a touch of anything, use fingertips as opposed to whole hands, etc...and all should work out fine. Also keep in mind, you've done this before, you'll do it again, and you passed well enough to make it to the line. These guys know that you have the skills to keep flying, even though sometimes they might belittle you about what they think you're lacking....but put most of em out there surrounded by weather, shooting an ILS to mins, with a max crosswind, to a snow covered runway, and their pucker factor might actually be higher than yours....cheer up, and keep flying.
