Combi-weapons are bad on a Librarian. You'll wan't to go after big things with him and his Force Weapon. And the only way you'll be able to get some good shots out with a Combi- is to Rapid Fire. Of course you could go with the Flamer, but when was the last time you wounded a Daemon Prince with a Flamer? Plus, you can only fire the Flamer/Plasma Gun(Rapid Fire)/Meltagun once, and that won't really be enough in most games. Then the Bolter is also Rapid Fire. Bad. See my point? You can't Assault when you Rapid Fire a weapon. And so the Storm Bolter is the only good choice.
