I’m a big fan of covering all bases, when possible. I recommend using a lav/bluetooth mirophone (try to put it on the inside, but don’t let it rub). I also recommend a boom microphone or shotgun microphone.
On the wedding introduction I’ve included, the wind was howling. I used two camcorders – one with a Sony ECM-CG1 and one with a Sony ECM-AW3 bluetooth microhone. I ended up using the audio from the bluetooth. Note: I did use the included sock and didn’t get any rubbing noise. Your Sennheiser should do well but I’d definitely have either a boom or shotgun, just in case. Good luck!!
