If you are going to be doing open taping....and the profile so to speak of the mics is not an issue, it is tough to argue that the TLs are the best value due to the multi patterns. That being said, if you are willing to consider other options, I would actually look at the Gefell M300s as well. You can get them in the same price range as the KM184s and I actually like them better than the Neumans for taping rock shows.
Just my .02
