I think I want a 6’0” medium spinning rod with a fast tip for hard and soft jerkbaits, and I also think the same rod would work for topwaters. I’m used to using 6’6” and 6’8” rods. For jerkbaits these lengths feel too long to me. I know many here use 7’0” and longer but for me a 6’8” is as long as I ever go, and for the tip down presentation of a jerkbait I want it even shorter. As for the topwaters, the medium power and fast action just seems right to me based on limited experiences working them (popping, twitching, walking). I feel this would be easier done with a shorter rod, and I’d make more accurate casts. 
 

Both of these type of lures are worked on a rod that is only under a load when either jerking the jerkbait, or working a topwater. When I snap the rod to move a jerkbait, that’s when I always feel the weight of a fish and this sets the hook. The rod wasn’t under a load until the snap so it has plenty of flex left in it to absorb the shock. A topwater is also barely bending the rod so there’s room to flex on a strike. This is why I think the two baits would work out well on the same rod, even with a fast action, and in spite of the smaller treble hooks they have. The fast action helps to work the baits better also, I think. 
 

My rod of choice would be a St. Croix Premier because of the foregrip design and light weight of it. Probably paired with a Daiwa Legalis 2500D-XH for a really lightweight combo.

 

I’m unsure about line. Fluoro sinks and might be better for jerkbaits but not topwaters. Maybe a copolymer? Yo-Zuri Hybrid in 10 pound test is what I’m thinking. Maybe braid with a fluorocarbon leader? Braid floats, so maybe it would work better for topwaters not to have 50-60 feet of sinking line out. Mono also floats, but I want a line that I could get at least 6-10 feet of depth out of a Rapala X-Rap 08 deep diver jerkbait and still do ok for topwaters. 
 

I mostly want that specific rod for comfort but a Premier is a pretty sensitive rod. May as well not waste it. Depending on the line used, this rod could also do well for light weighted plastics rigs. Texas rig, wacky rig, drop shot, ned rig, and more. 
 

Opinions?

IMO a JB and topwater rod are very similar.  I think there is more nuance to a JB rod, as far as action and power.  You can see how a popper or pencil reacts to every twitch, but you can only feel what the JB is doing.

The Premier is a good rod at its original price point, but now they're closer to 200 than 100$ and you're still getting AL oxide guides on their SC 2 blank.  There are quite a few rods at a lower price point that will outperform a Premier.  

It would be more than worth it to spend another 40$ and get a Victory.  Victory is so much lighter than Premier and the blank is much better quality.  The problem wll be finding a 6' rod.  

SC does make a 6'3 M XF walleye rod, that would probably be great for JBs and topwater.  Spend 200$ and get an Avid Walleye.
