In light of me not having an active subscription and having a limited supply of 1.6, I ordered a crapload of 2.0 today.
I love it but have been using 1.5 and now 1.6 for cost reasons and easier to mix with protein & flavor.
Not sure about pb2 but regular peanut butter was way too sweet in 2.0
Maybe I can handle 2.0 and whey without pb2.
So yeah Rosa Labs, you win, for now. Going to set up a backorder for 1.6 soon.
