First of all, welcome @nicolasptrsn ! Come on over to this thread and introduce yourself! 
I’ve been playing around with this a bit. I like the idea of floating thumb and all the muting goodness that comes with it. I’m just really used to having an anchor and it feels like, for lack of a better way to describe it, I don’t have any power in my fingers without something to anchor on.
So I’ve been doing movable anchor, moving the anchored thumb between pickup, E, and A strings. I think string switching is a bit faster with floating thumb, but I just can’t get used to not having an anchor.
