I use a Dobyns Champion 7'6" H-F rod for deep cranking. The rod says jigs, light flippin and c-rig. It is not what most would call a crankbait rod, but it works for me. With a tuned up Zillion, spooled with #14 mono, I can sling a DD-22 out of the county.
I discovered this by accident. I wanted to throw a DD-22 one day and did not have my deep crank setup with me, so I used the above setup. It worked well enough I eventually sold my custom deep crank rod because I no longer used it.
If you're willing to do a little experimenting, you will discover that all of your rods are good for more than one application. Simply ignore "conventional" wisdom, and give it a try. Within reason of course. I wouldn't use one of my light weight trout rods with 4lb test mono for punching; that would be stupid. I wouldn't tie a 1/64oz crappie jig on one of my heavy jigs rods either. But, right in the middle, I have two St Croix LTB 7' M-F rods that I can, and do, use for just about anything. From 1/8oz up to 3/4oz; jigs, plastics, cranks, spinnerbaits, etc.
If you find something that works for you, well, use it. Who gives a rip what somebody else thinks? And, who the heck are they to tell you you're not doing it right?
Being an old fart, who has been at this a long time, I ignore about 90% of what I read online. I've always preferred figuring it out myself.
