Zeke the fish you're talking about are smolts, the last phase before a mature trout. Steelhead do the same thing only larger. The markings that cover a 4" bow will be the same on a 6" steelhead while the 6" trout will be very close, if not completely, marked like an adult.
While I haven't seen a tremendous number of Crane Creek bows, I've never seen one with any color like a redband.
