I'm not sure if you like it or not, but I was told a single 6 ft sheer waterfall costs less than 3 small ones, and is less plumbing too. No hate at all, the design is beautiful I just like the longer singular sheer descents plus it's cheaper haha. I thought 1 long one was more expensive back when I was where you're at as many of the first quotes had them instead of 1 big one.
Keep in mind the higher you go the more noise they will make, for us that was a + as we back up to a busy intersection.
Regarding SWG, I think you will enjoy it over lugging jugs of chlorine to the pool and for some reason no builders here want to use one. My PB is still warning me about how much trouble it's going to be...but he's been doing the same thing for 20 years and is stuck in his ways.
