It sounds like your system is well suited to your needs, and I hope my comment didn't come off as a knock on that.
My post was more in reference to people who build elaborate brew sculptures or other types of permanent installations, and then plumb everything up with flexible hoses, barbs, worm clamps, plastic fittings, etc. even though there are few, if any moving parts. I even see this is the norm in many off-the-shelf systems, and it's just wierd how so many people just accept it as the standard way to do things. If I were to tackle a huge welding project, or conversely write a check for a couple thousand bucks and purchase one of those fancy brew sculptures, it would annoy me to see flex hoses and band clamps installed where they are not needed.
Then again, I've seen a lot of those stupid flex hoses installed on bathroom sinks that only need service every 30 years or so, but I guess it saves 2 minutes on the installation, and makes a few extra bucks in sales to Home Depot.
