Thanks for the suggestions.
I think the AT PRO 70 is not really usefull for rockconcert with its 123 dB SPL.
Line Audio CM3 would certainly have my attention but with my new Nevaton's, which size is almost the same.... no benefit now. I have only used the Nevatons twice, and they are promising. But, like the Line Audio a bit difficult for heavy stealth-situations.
Both countryman and DPA can do very good things in the right location, but I stepped away from omni a long time ago to get rid / heavy reduce crowdnoise.
