I am wondering what size deba should be used for certain fish? For example 20-25lb rockfish. Is a 210 too big? I've recently been adding more single bevel knives to my everyday work and want to try a deba. I have a feeling I want to go smaller then I think but don't really know. I've been looking in the 190mm range. Also if anyone has any recommendations for a good carbon workhorse deba I would love to here them.
