I strongly dislike Royal/Royal, I tolerate White/White (though royal trim makes that look way better).
I think 4 sets of Uni's is the way to go
Home: Royal on White, Navy on White
Away: White on Royal, White on Navy
If they dropped Navy all together I wouldn't complain, but I think it looks especially good in the daytime.
I wish the default away uniform was White on Royal. The Houston game last year was the best look all season.
The team does White on White way too often.
