Apparently, signature that I used from 2006 no longer tolerated so now deleted.
If you don't hang in it for to many nights you can untie the knot and change the hammock length to experiment with the length vs comfort
I have done that quite a few times to get the best lay.
I agree comfort is tailored to your height, and sleeping style.
I just experienced what you are talking about. Because of this thread I decided to rewhip my table cloth hammock to 7 feet. No calf ridge, and it is very comfortable! I mean like, real comfortable!
I'm short at 5'6"
