Hi idlewild,
I would treat the choice between Talalay and Dunlop as a preference choice … not as a “better/worse” choice in either the comfort or support layers of a mattress (see post #7 here).
I thought about this when I first started the site but in the end I decided to make the subscriptions “opt in” rather than “opt out” so that the members have complete control over the forum posts or categories they are subscribed to. I thought it would be less “intrusive” that way (although I still go back and forth to some degree in my thoughts about this).
