Looks clear enough. I can tell you have a spider system there. Never have been fond of them, though they serve their purpose. I think you'd be better off installing a metal graduated duct with some snap-lock pipe going off to your registers, though I know as well as you do that's going to incur more cost than you likely had figured. I've never been a big fan of flex duct or spider set-ups. If your roof/rafters allow for a straight shot of trunk line, it's worth pricing. Have someone make some up and you can still install it yourself and save some cash. Easy to cut holes in the trunk and come off with snap-loc, then wrap it up and your good. just an opinion, I have beat a lot of duct together, but that was years ago, and I was just a gopher, wasn't a layout guy.
