Hi vram,
I normally scan all the threads looking for specific questions but this thread has been moving very quickly so I’ll answer the questions I’ve seen and if I miss any let me know.
I have no experience with either cover because I haven’t slept on either of them and “feel” is completely subjective so I really can’t answer this for someone else. In general I keep my comments to guidance about quality and value because PPP and "feel’ is much too individual and subjective to give any meaningful guidance for someone else except in the most generic way. I do know that both are good quality covers and quilted with wool but they would be a better source of information to try and describe the “feel” or the finer details of each of their components.
You can see some comments about the lanoodles topper in post #38 here. A thin shredded latex topper is more of a feel and surface softness layer than a significant pressure relieving layer. Contoured or “pillow” surfaces would be similar to convoluting in the sense that they would have a different “feel” and a little extra softness. There is more about the different types of softness in post #15 here. The lanoodles is more of a “feel” softness that adds some extra “cush” with a bit of benefit for pressure relief as well. It can add some extra softness with less risk of alignment issues than solid layers because the shredded latex can “flow” around the more protruding body parts (like the shoulders) that need to sink in more but will be “compressed” and be more supportive under the larger surface areas (like the pelvis).
If you can feel the difference it makes and it’s a significant improvement in terms of PPP it would be “worth it” but they would probably be a more valuable option for thinner mattresses (in the range of @6" - 8"or so) than with thicker mattresses. The benefits would be less with thicker mattresses because the mattress would absorb more of the compression forces before they reached the adjustable foundation. My “baseline” would be a firm slatted base with the mattress doing the work and I would only add an adjustable slat option if it provided a noticeable improvement (or I was convinced it would) that was significant to me.
The overall process I would normally follow would be to “force yourself” to choose a single “finalist” at each store you are dealing with based on a combination of PPP (most important), quality (all the mattresses you are looking at are all good quality with no “weak links”), and value (are some of the more premium mattresses you are considering worth the premium cost based on any extra features they may have compared to others with similar materials). With your online “finalists” that you haven’t tested then your confidence about how suitable they will be in terms of PPP based on a combination of your conversations and testing experiences and your ability to re-arrange or exchange layers (or zones) would be a more significant part of my choice. Your own knowledge about where you are in the range of the “princess and the pea” to “I can sleep on anything” scale would also play a role in the options that were important to me. With local testing I wouldn’t do too much analysis of the layering and would let my body decide which was the most suitable in terms of PPP. With online choices there is more “thought” and intuiive judgement involved because you can’t test them in person. Final choices can be difficult (it took me weeks to decide between my finalists !)
If I’ve missed any of the questions you had let me know 
@ Lisa_mocha:
The last time I talked with Foamite was some time ago but at the time they only offered Talalay in a single ILD. Of course they may have changed the options they have available since then. Their site says they use Dunlopillo which used to make Talalay Latex in England but went bankrupt in 2008 and now it’s just a name. In North America Latex International owns the trademark which means that any latex that is sold as Dunlopillo would be Talalay latex made by Latex International.
