Is the route on the MR hard to navigate? Is it easy to get lost and find yourself cliffed up somewhere?
There is really only one tricky move in the Final 400 which is actually getting into it. There's about 8-10' of exposure with bad handholds getting up to a ledge. Once you're on that ledge, head straight up and go a bit to the climber's right. If you go too far to the right, the terrain will become 4th/5th class. It's easy and fun movement all the way to the top. There are also plenty of other variations that stay 3rd class. Enjoy.
