This is my standard response to anyone looking at the 406x's. Not trying to convince you NOT to get them...they are fantastic mics.
Anyway, I owned a pair of 4060's (>MMA6000) and loved them.
Since then I sold them and got the Nevaton MCE400's and like them so much more than the DPA's. To me the Nevaton's sound more like the actual show and seem to be more forgiving at a less than great sounding show. Another bonus is they are WAY cheaper (I think there is a pair in the YS for $325 for the pair). They do require you to keep the XLR connectors, but otherwise I personally prefer them to the DPA's (and that is regardless of price). They are also slightly larger than the DPA's, but I haven't had a problem with that.
I think you live in CO...if you ever want to borrow mine to try them out, let me know.
If you're looking for smaller option you might also want to consider the Countryman B3's. I haven't used them, but a lot of people have switched from the DPA's to B3's as well.
