Plano makes lots of different specialty boxes. Go to their web site & find out. Some guys are fine with their cranks all kinda scrunched together. Me, I kinda like individual compartments for different baits of the same style and different boxes for different bait styles, primarily so that they don't rub against each other as much in transit and it makes knowing. what I got a little easier. I like using hook bonnets also, just because I ain't fond of sticking a hook point in my finger while I'm digging through my crank collection, and those often take up extra space, so fewer baits fit in each trough. Therefore DD cranks get a box - med cranks get a box, wake baits get a box and so forth.
If a box fills up I will get another box rather than blend. Med. divers with square bills for instance. Taken a step or two farther ( like many of us do) - Wiggle Warts get their own box. DC8 Timber Tigers get their own box. Norman DD22's get their own box as do the large Fat Free Shad baits. and so on . . ..I like leaving extra room in each box, in case I should happen to acquire more Wiggle Warts or Timber Tigers or whatever.
I understand that it means buying a few more boxes and I'm ok with that. Be on the lookout for sales/closeouts. A couple of years ago, the Walmart in my area all closed out on crank boxes, like the one pictured in the previous post - $4 a hit. By the time I found out, Walmart "A" had 3 boxes left and I got those. A few days later, driving to work I realized that I was driving past a few other Walmarts. I ended up with 10 of those boxes altogether from 3 different Walmarts.
This year they had the 3600 size regular boxes closed out for $2.88. I've bought 10 of those so far. Besides fishing purposes, those boxes are a good size for organizing random loose stuff in my shop. - specialty saw blades, random drill bits, stuff like that.
