The solo loop is a much more like mechanically sound and visibly sound option for the apple watch ultra compared to the regular sport band so i can recommend it. The storm blue because you know kind of this navy blue. It's a super boring color but it's the only currently offered color that i think would look good on the ultra they do have a nice bright yellow and the ultra has that yellow ocean band. But i saw that in a store i don't think the ultra goes well with yellow because it has the orange accents and i get i don't  think it's a good match with yellow but i might try we'll see.
