Wow.
I remember back in the day when we were afforded like 9 days to install a multi floor hydro, painted out and cleaned up. We actually used antiquated tools like the conduit bender (remember that?), emt straps, j-boxes and bushings on the fitting ends. In that day, those who used aluminum or steel flex or all over the cartop were scorned. But they were out to prove just how quickly they could install, but cared not much for pride in workmanship.
