1. How often have people had lens leaks on masks (other than brand new ones, or one that have been freshly re-assembled)
Has never happened to me.

2. How is dropping a mask and replacing it with a spare, better than not dropping it in the first place by ensuring the strap is retained under the hood.
It isn't.
Here's my take on this....
Until very recently, I was a "wear the mask strap under the hood" supporter. Now, I wear it over the top of the hood. Why? because I tried it that way and find it easier and more comfortable after years of wearing it under the hood.
I really don't see what difference it makes. The mask is a fairly important piece of kit. You need to look after it and check it thoroughly before and after every dive.
I have to admit (shock horror) that I don't carry a spare mask on most of my dives.
