Handcraft Mattress owners, your input please!

We've done the home cut foam route, and with 5 inches of foam factory's standard stuff and a memory foam topper it was almost too soft, but worked well enough for the last few years. However, we're about to take the plunge and buy ourselves a fancy, "real" mattress for the boat. I've heard only great things about HMC's latex mattresses, and greatly appreciate their fabulous customer support, but if anyone has any 'personal experience' answers for me, I would love to hear 'em.
What model and thickness did you go with?
Did you get the fancy bamboo quilted pillow top?
Does the medium firm latex (4 ½” 5 ½” or 6 ½” with Pillow top) have enough give for the boney, achy hips of a relentless side sleeper?
And if you went with the hinged option, can you feel it?
I suffer from being a light sleeper - helpful when we've been boarded in the past, annoying on the daily - and so I take my mattress comfort very seriously. My fiance could sleep on a rock, as long as that rock is on the boat.
