LImp and greasy is how mine gets with co wash, I have to use no poo.
Creme of nature is a good no sulfate shampoo that's under 4 bucks for a big bottle.
Activate makes a good no sulfate shampoo.
No poo and low poo from DevaCurl are good cleansers. I prefer no poo myself but many prefer the other.

Soft water is a trip isn't it?
Hard water wasn't all that fun when I was in the city but at least my suds from my shampoo would rinse out and my conditioner would rinse out. but my hair was def dryer there and less curly so it has it's own set of problems
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
