These are the cranking rods I either own now....OR have owned in the past, I'll give you my thoughts on each and let you take it FWIW:
7'10" Heavy power/mod. action Legend Tournament "Magnum Cranker". Good rod for bombing big crankbaits like SK 6xd's, lots of back bone for ripping baits out of grass, and pretty light for a darn near 8' rod............but it also almost $300. What I didn't like about it, is that I tend to fish baits on the lower end of it's rating more than it's mid to upper range. It was a little too stout IMHO to load up and cast SK5xd's very well, which is what I use about 80% off the time for my deep cranking...........Also it has about ZERO uses other than deep cranking. I did not like it for shallow or lipless baits, and space is limited in my boat so having one rod for one bait was not getting it done for me. But if you want a rod to throw 6xd's, DT20's, and other 1oz.ish size baits this rod is almost perfect for it.
7'9" MH Kistler Argon "cranking" rod....I never got to use this rod enough to form an opinion, it broke on like the third fish I ever caught with it, and Kistler did NOT have any in stock to replace it with, nor were they too concerned with helping me out warranty wise sooooo......moving on.
7'6" MH Abu Veritas Winch: Not as whippy as some cranking rods, it fishes the 5xd's better than the big St Croix, and handles 6xd's OK...has more versatility than the St Croix, I also toss bigger square bills (2.5 etc) , and 3/4oz. lipless cranks with it, nice and light, and balances well. This is the rod I currently have, and time will tell if I like it for the long haul.
7' MH/Mod St Croix Mojo "crankbait".....this was a great rod for square bills, mid depth (wiggle warts, bandit 200's, etc....) and 1/2 oz lipless baits..........AS LONG AS you were not around grass, which is where I do most of my cranking. Even with braid, it loaded up too much IMHO to get a clean "pop" out of the grass, but other than that it was great.
7' M BPS Cranking stick....even though it was labeled as a Medium power it popped baits out of grass better than the Mojo, and it handled everything the Mojo tossed just as well and was a few bucks cheaper to boot.......for some dumb reason I got rid of this rod on a whim and kick myself for doing it.
7' M Abu Veritas Winch....like the BPS Cranking stick, even though it's a Medium power, it pops the baits out of grass better than the Mojo, plus it's lighter and balanced better. This is a rod I currently have, and I fish 1.0 and 1.5 size squarebills on it, 1/4 and 1/2 oz. lipless baits, mid depth baits (wiggle warts,etc..) and I have even tossed some top water with it, which I didn't do with the Mojo because it loaded to much instead of worked the bait. I like this rod, but honestly, I should have just kept the BPS cranking stick and been done with it.
