I know that hypers are more prone to wind at outdoor shows, but when it rains, I mainly use hypers for that very reason, so you dont hear pitter patter! I ONLY record amplified music, and the ONLY time I hear rain noise is inbetween songs
I just use your average umbrella [next year Im investing in [2] Gustbusters] and its NEVER a distraction to me. I RARELY hear the rain even inbetween songs, and when it is soft and barely audible inbetween songs, it makes the recording that much cooler, at least IMO
This summer I even ran my mk4s during the rain and even with those cards, its BARELY audible inbetween songs. Obviously it depends on the nasttyness and power of the rain, but if youre recording loud PA stuff and youre not like 500 yards from the stage/sound source, you should be alright most times. And if the rain is SUPER NASTY, then most likely, they will postphone/cancel a few sets until it clears up, ala All Good 2013
Now if youre running omnis, well, youre pretty well SCREWED
