Something to think about for those who are constantly putting their mic's away. You can only drop something you have in your hand. Every time you pull it from the mount, remove the cable start walking with it in your hand you are sending the odds that you will drop it into the "it could happen" territory. The cable connections on my 414 TL II's is very snug and I approach them with extreme caution every time I set them up. I always handle my microphones with extreme care but I try not to handle them at all.
As for covering mic's, I used to do that but I had a couple occasions of leaving the studio and returning the next day to resume the previous evening's work only to discover I'd left the cloth bag on the mic for the first 30 minutes of the day. I'd get up to check something in the iso room and discover the bag is still on the mic.
All the microphones I've examined seemed to have some kind of fine cloth on the inside of the windscreen. I always figured that would keep out most of the particles.
Don't get me wrong, I do believe in taking care of my gear. I know there is dust all about. I try to minimize my handling of most of my mic's. I tend to use the same mic in the same applications often so many are always in the same stand and they always travel together. The only ones I move about more frequently are the LDC's.
My cables are meticulously coiled and hang on hangers in my main room. I keep a few specialized short cables in the iso room. I regularly refresh my cable layouts for continuing setups as I hate them to look all tangled. I use little doubles sided velcro strips to wrap them into little looms to keep them neat. I hate to leave a cable running across the middle of the room over night but I have to sometimes. I would love to have multiple panels in my room so I could keep the middle of the floor clear as much as possible. When I must leave a mic set in the middle of the room over night I will wind the cables from the panel to the stand (therefore not handling or moving the mic).
