I like that the "black" is not actually black. It's more of a charcoal. I think that would be much better for ISU.
At this point I would settle for
*White helmets
*Gold helmets
*Striped current helmet
*Gold jerseys again
*Cardinal pants on the away uniform again
Pretty much anything else to mix it up.
I also want the helmet stripes, but let’s assume that doesn’t happen.
Your other four possibiities (along with the standard current combos) offers at least 7 viable options:
*Cardinal helmet-cardinal jersey-gold pants (standard home)
*Cardinal-white-white (standard current road)
*Cardinal-white-cardinal (alt-road/return to standard road)
*Gold-cardinal-gold (alt-home)
*Gold-gold-gold (alt-home)
*White-white-white (alt road)
*Gold-white-gold (alt-road)
Personally I would stop there (no all-red, no white helmets or white pants other than all white, for a few examples).
I’d be surprised to get even one alternate helmet, let alone two — even sticking with a single hat, we have multiple possibilities within our current design and color set to keep things “interesting†with no redesign or the need to stray into gray/black.
