Hi Phoenix,
Brooklyn Bedding has a new offering that includes 2" of Talalay over 2" of Dunlop over a high density poly foam. I do realize the poly foam isn’t comparable to the support layer of latex but this combination may provide similar comfort for $700.00.
Perhaps that’s a poor assumption on my part.
The more I research the more fog drifts in. 
Hi PapaMike,
Yes … they have been working on their new mattress for some time (see my comments in posts #6 - #10 here).
It’s certainly a great quality/value choice and there is little to no risk in trying it because of their free return policy but it’s an apples to oranges comparison and would be very different from an all latex component mattress both in terms of feel and performance and in the ability to customize the mattress after a purchase. There is more about the differences between a latex/polyfoam hybrid and an all latex mattress in post #2 here.
The only way to know whether any mattress will be a good “match” for you in terms of PPP with any certainty will be based on your own actual experience.
