I have a reasonably long 40-45 mph decent on one of my local rides too but I'm perfectly happy to just tuck in and let the bike roll.
If you are commuting, then nobody is chasing you and you aren't trying to reel in a breakaway. Why pedal like mad when you are going that fast anyway and are better off to just lower wind resistance?
As to the OP's concern that his small ring will max out with a 14T, uuhh, that's why the maker gives you a big ring. Feel free to use it.
