Yes. There are way too many variables to be able to figure out a rule of thumb. I own a lot of hammocks, and each feels different. I guess the only way to find the perfect hammock is to try as many as you can...
I don't think that other people's experiences will help you. But for what it is worth, I'm 5'4" and my favorite hiking hammock is the 10' WBBB. So far I haven't found another hammock that I like equally well.
