So I've decided to get a couple boundary mics as well as some others. Any recommendations between the Bartlett and AT U851? The Bartlett has the advantage of a permanently attached cable, which seems a pain to store but everyone seems to recommend that. The AT is a little lower profile. I was at a show last year that used the AT and it seemed to do OK. I will probably also get some AT U853 hanging mics, but I assume they are so different that there would be no advantage in sound consistency to keeping within the same brand.
