I'm not sure if the issue is due to the UQ sealing but for what it's worth on my Eldorado it took me a while to get rid of the calf ridge. What finally worked for me is this: I typically would get in the hammock and then sort of slide my feet from the INSIDE of the hammock to the OUTSIDE to smooth out the fabric and slide into the foot box. One day I just slid my feet from the OUTSIDE of the hammock towards the INSIDE and I just settled perfectly into the lay with no ridge at all. I can consistently find that sweet spot now by repeating that slide in from the outside movement. I hope I'm explaining it right lol.
edit: This video might help explain what I mean, if the link doesn't do it for you fast forward to 4:38 in this video. See how he's sliding his feet to make the foot box? Do this but from the opposite direction, from the outside edge towards the inside..ie from this kid's right towards the left/center of hammock.
