Follow up update... Dealing with the pressure!

Good morning all, just a quick post between Sunday morning activities...

Upon waking up and prior to heading out this morning, I popped out to the shop to take a quick peek at the pressure gauges. Sure enough the system is holding steady.

I have some long term durability concerns for using the rubber hoses, however I realize that I am pretty much going to require hoses to connect the compressors to the manifolds at least as the compressors vibrate and I need the flexible connection to keep from transferring the vibration to the rest of the plumbing, and in turn to the wall studs, and the rest of the house...

My options as I see them are...
#1. accept the fact that the rubber hoses will eventually spring leaks and fail (they all do) and replace them on an as needed basis.
#2. Upgrade the output side of the system between the filtration system and the hose reel adding possibly a hard drop at the front of the shop using a snap together system such as Rapidair.
#3. Run a system similarly laid out to the rapidair mentioned above, but with sweat fit / soldered copper pipe.
#4. Same as the 2 above, but using black iron...

I know I am overthinking this at this point, as it is all set up and working so well, but I want to have my head around any future possibilities.
