If the primary away was the same as the home, I think this would be a decent to good set with the two alternates. Instead it kinda seems like hodgepodge.
I agree, helmet stripe doesn't look too jarring. It's kind of a poor man's Seattle stripe, but the jersey itself isn't bad at all. I do wish the orange stripe on the pants wasn't cut off.
These are fantastic. I really think the exclusion on black on the Green, and White sets help the black set stnd out on it's own as an alternate, without muddying up the cleanness of the Green and white.
