Glad someone raised this before anxiety got the better of me. 
I enjoy L&C more the harder the lift is - not technically, but physically. For me its a strength thing, but that said, I'm not really into muscle worship. It's one thing for a hot girl to pick up someone bigger than her, but another for a hot, trained/athletic girl to be put to the test. 
An athlete would have no problem hauling me around. Which would be great for a while, but I'd always be wondering about her limits. 
I am a picky, picky man 

 Probably for the best that I remain single. 
The test thing is a big part of it for me. I think thats why I like multiple carries and odd positions. 
I kind of dig the sadism thing but I'm not really the kind to go out and hurt people. I'm more of a mad scientist than a torturer. 
I remember there was a wave of Brazilian L&C videos over youtube where it seemed like the girls were being forced to carry other women around. Might be of interest to the OP if he hasn't already found them?
