Rather than just saying "it's usually a good idea to put the smaller block first", I like to think of it as shortening the main-line logic. Whenever one side of an if-else winds up being a short-circuit exit (last, next, return, etc), I find it's much cleaner to just put that by itself to show that I'm figuring out how to do the short-circuit. Then, the else disappears and you've managed to reduce the indentation level by 1. In my book, that's always a Good Thing™.
All of which is probably a fancy way of saying that the rewrite (above) looks good, I'm just disagreeing (maybe) on why it's better. :-)
