I would say its personal preference first. I learned to fish with a medium heavy rod, so that's what I reach for first. Using lighter baits means a lighter action.
For crankbaits, I usually consider the size of the bait to figure out which rod I need. Since most deep divers are 3/4 oz or heavier, I use the medium heavy. It really does come down to preference. But, for the money, these rods are the best you can get. If you are in a position like, college student, then a rod that is cheap in price but high in quality is the best thing. Hope this helps.

Any Crank Bait i use that dives from 0ft to 6ft.The medium action is my choice.Anything that dives under 6ft Medium hvy is best i feel. You need that extra power to get a good hook set with a Crank Bait this deep because of the resistance.And the bigger bait profile.Plus hook size.

The weight of the line and lure usually determine which type of rod weight is best for that lure. The lure weight will be listed for each rod.
When using a lure near a lot of weeds or wood, you want a heavier rod to pull the bass out of the cover.
Hope this helps!
