I don't have anywatch tower setup and maybe I should have one. Maybe I do that in a near future.
When a Lightning node is online 24/7 why would you need a watchtower for it? From my understanding of LN only reason I would consider an independent watchtower if you want a protection for your channels should your Lightning node go offline for some unexpected reasons. If offline periods are rather short (say less than ~30min) and scarce, I wouldn't bother to setup an independent watchtower. (I might be wrong, though.)
