With the depth range that you are want to crank, I would suggest looking at the CBR843. I have this one and love it for medium cranking. It will also work very well for shallow cranking and will handle a DD22 if the need arises, but I would like to get a CBR903 for a DD22.
Just remember this, there will be some slight variations in the action of a cranking rod. After deciding on a Loomis rod, I went through every 843 in the store to find the one that I got.
