I’m in the same dilemma with these two.

I have the old 4UP StaDry, the first waterproof lightweight carry version that later became the Players 4 StaDry. I also have a regular 2019 Players 4 and have ordered the 2020 Players 4 Carbon but its not here yet. I would say, StaDry works if you play in a lot of rain. If not, the no-leak zippers are not as durable and might give you trouble over time. The thing that I look forward to with the Carbon will be the new legs. I have had several stand bags where the aluminum legs have been bent by the airlines. That problem should go away with the carbon legs. Also will be the lightest bag yet. I still walk pretty often and prefer to carry so the lighter, the better, for me. I don't carry a lot of extra stuff so the minimal storage capacity will be okay for me. I'll let you know in a few months how well I'm liking the Players 4 Carbon.

Thanks you I really am leaning toward the Carbon after reading this and I’m happy you
told me about the zippers because I rarely play in rain. Thanks you very much
