I like using different models of 3700 size boxes. I carry a soft pack that fits several of them plus a spinnerbait box. I fill different boxes with lipped cranks, others with lipless cranks, others with various soft plastics, topwaters, etc. For most situations I am familiar with the water and I already know which few boxes I want to carry. If I travel I will take a wide variety and after a look at the water I know what I will feel be throwing and will load those boxes into the pack. It is an efficient system for many people and one that that has worked well for me since I decided I didn't need to carry enough tackle to stock a sporting goods store. If you fish tournaments as a non-boater the guy you fish with will also appreciate it.
