I too am very curious here, I've been told that the reason TC is so commonplace is because it is far and above easier to keep sanitary, no threads or nooks and crannies to hide bugs. I know it was hard for me to connect TC connections but I only did it for a week. My buddy that worked there did them so fast it wasn't funny, due to using them daily for so long. If you think they're that hard to deal with, I've seen more expensive spring loaded TC connectors so that putting on the clamp part is easy and then you just tighten with both hands. I have, though, read a decent amount of people here talking about using DIN (I'm unfamiliar with SMS) but those are threaded right? Therefore have a higher chance for critters to build a colony in the dark dreaded places?
I'm very curious to understand more here for sure!
