Hi SD2000,
I would keep in mind that 100% natural Talalay isn’t organic and the only organic latex is 100% natural Dunlop that is certified organic (see post #6 here for more about organic Dunlop latex).
Post #6 here also has more about the different types and blends of latex but the choice between them would be a preference choice not a “should or shouldn’t” or a “better worse” or a “right or wrong” choice.
There is also more about the differences in feel and performance between Dunlop and Talalay in post #7 here.
