We've used those Jerry bags before; I'll warn you though that they are not really that well made or sturdy, and they are quite tippy. You like LL Bean stuff ... my DD has used one of their rolling backpacks for years, and it fits her size 7-1/2 skate, guards, chamois, jacket, pants, and in the outside pocket, makeup and hair stuff for competitions, quite nicely. It's taken tons of bumping and battering and it still looks great.
Zucas ARE FUN! THE WHEELS FLASH! You can sit on them! You can stage Zuca bag races with other kids sitting on their Zucas! Actually, around here, they all have them up to about age 12, then, they are considered to be juvenile and silly, and the kids switch to LuLuLemon gym bags (which do work well as skate bags actually and look great, just really expensive). It's a status symbol thing. My coach actively discourage them, because your skates end up bouncing around under a pile of stuff, and they are way too expensive for her taste.
