Personally I'd never wrap a large snake around my shoulders or neck. A large snake can quickly wrap around you, just do a search for people killed by large snakes, it's the only way they can really take you out. It's better to use multiple people and handle them at about waist height like in this photo below. And it's best to always have multiple people around when you do handle them in case anything goes wrong. When I'm alone I typically just assist the snake to get from one tub to another or up onto the table. She is getting too big to risk getting wrapped up by her.
That is a given for giant species, like in your photo. But we're just talking about 6-6.5 foot carpets/snakes around that size range, which don't require multiple people to handle and won't take you out.

I definitely recommend Serpwidgets for measuring your snake. Just put them on a flat enough surface, place a ruler or something down next to them, and get a picture from directly above them when they are in one layer (doesn't have to be straightened out.) You can put this picture into their website and just define the ruler and draw a line along your snake and it calculates their length.
