Omaha is among my top 3 favorite concepts.
I love curl routes, myself. If I could throw all curls to really large-bodied WR all day, I would, with the occasional comeback in there.
I'm also a fan of the deep dig.
I rarely throw 4 verts; I'm afraid I'm gonna get warp picked. I also rarely throw corners or banana routes; I'm also afraid of picks on those throws, for whatever reason.
