Hey now, I am only 6 feet 1 inch tall and I have been recording concerts for a few years now maybe 80 or 90 shows so far and I have had good performance with a few different microphone setups. The least expensive very good being the Sony 957, (@ $175.00 US) The very best are my DPA 4061's with a Core Sound battery box (to line in), they are truly the best I have heard so far. I am now using them with two Sony HiMD 910's so I can get 3 hours and 8 min in PCM mode with out having to swap out a disc. This set up is by far the most comfortable and stealthy I have ever used. I use the DPA foam wind screens on the 4061's and simplly stuff them in my ears, the kevlar flesh tone leads are in a binural "Y" and tuck neatly under my beard, at 6'7" your work should be at least as good as mine probably a bit better with respect to crowd noise! The real controling factor is your seat (microphone) location I find the best results are a seat location near the center line in the first 15 rows, idealy the first 5 rows, so tickets are the real expense (not the DPA 4061 microphones @ $980.00 US) It seems that all the artist I like most almost all use Meyer Sound Line Arrays and frequently Meyer Sound Studio Monitors as toe ins for the pit area up front, where I like to be, and that really helps the quality of the recording when your lucky enough to be up front in the pit.
