I'm new to hammocking and have been trying out a Hennessy hammock with the classic, bottom entry opening.

I'm not sure if I'm laying at the correct angle and position, but I'm finding that, although I'm generally comfortable, the centre line of the hammock with the velcro strip seems to be at a higher tension than the other material, and it's digging into my leg/knee. I've heard of calf ridge, and suspect this might be similar, but depending on where I lay it's usually a bit higher up - above my calf and sometimes around the side of my knee.

Is this typical of this hammock, and if not, what tricks could I try to alleviate it?
