When I hear "ribbon tail", I don't think of that as having any thump, but if what you are fishing has thump, then I would say you're on the right track. If I were to pick a worm (from the Do-it line up) for night fishing, my first choice probably would be the Kutter based on its smaller size and aggressive tail, my second choice would be the 6.5" Ringed Ribbontail (which is only available in a pro model) because the ribs are much more pronounced than on the 7" giving a very prominent body while still keeping its overall size down, and my third choice would be the Stump Thumper (but I would pinch it down to 8" or less). As an alternate to a worm, you could also fish a swimbait successfully at night (depending on your cover).
