I’ve used Plano pocket packs since the late 80s to store different grubs and it always gave me a nice selection of different colors and sizes. One side was just nothing but grubs, and the other side was series of different jig sizes.
I never need more than five different colors in a trip. If I did, I just had another pocket pack, but most of the time was focusing on one single color any particular trip.
Each year I’d buy five new colors to try for the year and see how they did and stacked up against the results of previous years trips.
