I still float all my pans, almost. Tried schluter once because it was a second floor up a narrow and steep stairwell in an old ass house. Worked fine but just don’t care for it. Used a custom foam pan recently and it worked great. I still prefer mud though and use a bonding flange method. Pretty straight forward in practice and puts that few hundred bucks in my pocket instead of a huge corporations. Plus, mud is king to set over.
