Ok, somehow I was under the impression that you had 7 layers of latex on hand (excluding the topper) so I was confused about what you were going to try next. But I see that you're just bringing yourself back to the six layers . . .
Maybe the density difference is why I'm using 36 ILD and you're using something a bit lower. I've been thinking about this density issue and wondering if I should order a natural layer to check it out. But my curiosity hasn't been able to overtake my inertia.
