I'm a big fan of Bill Norman crankbaits. I have lost many, but I also have a couple that I have been using for longer than I care to mention.  There are, however some of this brand that will likely never see water again.  The majority of those are Deep MIddle N.  Marketed to target a certain depth, I feel they were targeting loyal users of their other models. 

Does a particular model of your favorite crank rank so low on your confidence list that you not only refuse to purchase another one, but never reach for the ones in your tackle box

I am a sucker for Norman cranks, DD22's especially. Ill buy every lot that I can get my hands on. I don't know why but when I choose a big crank its a norman over anything. I am a huge believer in matching the hatch the deep middle N is just the right size at just the right time. When the fish are hanging in 8-10 of water and the forage is about 2" long. They produce well on the smalleys late summer into the fall.

You're right, they have a place and time.  I get frustrated when I put what little extra money I have into something that doesn't come close to my expectations.  My problem with this bait is the fact that a deep little n can cover most of the same water and I'm to lazy to either switch  to or give the middle n  a fighting chance. Guess I'm just going to have to leave the other Normans in the truck so I don't have a reason NOT to throw it.
