All my jigs, except a few Buckeye Mop jigs, are from Siebert Outdoors, and do not require any trimming.  Trimming makes them stiffer, for anyone wondering.

I have the jig and terminal boxes and love them.  I keep looking at the crank box but I'm not sure about the size relative to the Plano regular crank box.  I use a regular milk crate and any thicker and it'll be a tight squeeze getting them in and out while fishing.

Same boat, so to speak.
