As for your questions. I'm not massively into this subject, so I can't offer a very broad response. I'm also perhaps a little biased, as I live only a ten/fifteen minute drive from Loch Ness
The least I can say, is that I've heard enough first-person accounts of Nessie sightings, and seen enough still/video evidence to convince me there is at least something in the Loch that is above the normal. Perhaps this would be the most fascinating to me, I dunno, I think any Cryptozoological discovery would be fascinating!!
