I just completed my O/W cert this weekend. I found it a lot more comfortable to put the mask on my forehead when floating around that around my neck but my instructor said that I owed him a 6-pack of beer every time that I did it. If he had collected my debt, he would have got several cases.
I don't see the harm in it but I'm a newbie.
Trust me, when it falls off, you probably won't feel it go, and they don't float. Generally you can't tell where you were when it fell off, and unless you are very lucky, it's time to cancel the dive, and apologise to your buddy for being a numpty. I know, cos I've done it, and it wasn't a cheap mask either. After bobbing about on the surface for 30 minutes while my buddy did his best to try to spot it in 2 metre vis, I had to concede defeat, the afternoon dives were stuffed as well as there was nowhere to get a replacement in time.
If you aren't distressed when it's on your forehead, you will be when you realise that it isn't anymore!!
