@roosterfire: My impression was that Vita Talalay makes the highest quality talalay latex in the world. For example, their talalay latex is used in the mattresses of this large Swiss company, which probably makes the best mattress spring units in the world: Sleeping systems – Hüsler Nest
Their latex is also used by Savvy Rest, which Ken Hightower mentioned on another thread yesterday, see comment #4 here: https://forum.mattressunderground.com/t/trying-to-decide-on-the-right-latex-hybrid-mattress
