Was it the saddle? The bars? The reach?
Any bike should be comfortable. If the Cross Check was uncomfortable and you can't narrow it down to something as simple as the saddle or the height of the bars, then move along.
An uncomfortable bike will not magically become comfortable later.
If it ain't true love (even if it's challenging true love) keep looking.
(I've ridden both Aurora and CC, and felt passionate love for the CC. If your passionate love was for the Aurora, then go with that. You know what feels best, and no-one else can tell you otherwise.)
BTW: bike weight doesn't matter nearly as much as bike fit/comfort.
