That is the funny thing about jerkbait rods, the flex need for fighting the fish is not good for working the bait and me and a few guys have done this experiment over and over for years. First of all, if you are using a 7' rod for jerkbaits, you are either 6'8" tall, hitting the water when ripping or you are using the sideways sweep which means you aren't getting the bait to work at its maximum depth. When you rip a jerkbait you want to do it on slack line, that is what gives you the most erratic action, when you do this with a cranking rod, you rip the bait, the rod flexes and since you already have slack in the line it causes the bait to move slightly forward with little sideways movement. In order to get it work more erratically, you end up pulling the bait on tighter line that when you need with the fast action rod so now you are just moving the bait forward with the nose pointing a little left and then right instead of the bait darting and diving, trust me, you can fight the fish better when hooked up but you will get less than half the strikes that you would normally get with a properly worked bait. The only time the cranking rod is the most effective is when the water temp is in the low 40s and you need long pauses with short pulls with little action, that is when the cranking rod really does a good job. In 2004 we used a few different rods for jerkbaits as there was a big discussion in our club about which kind of rod worked better so we stated an experiment between 4 guys starting in early fall with floating jerkbaits, into early winter with suspending jerkbaits, and when using the fast action rod for the floating versions there was no comparison, number of strikes and number of fish landed was better the 4 to 1 versus the cranking rod. When we hit late fall and into the suspending jerkait bite, the numbers got closer but the fast action rod was still better than 3 to 1 in strikes and 2 to 1 landed because you are going to loose more fish with the fast rod, that is the bad part. When we got into the really cold water when jerkbaits were still working, that is when the cranking rod was much better, strikes were the same but fish landed was 3 to 1 in favor of the cranking style rod and at that time of year you often get "nippers", the fish that just nip the back end of a bait and get 1 point of the rear treble in their lip, the cranking rod was good at landing those fish while the fast rod would loose all but a tiny few that were hooked like that.
