I also fish from a kayak but about 50% of the time. I usually take 5-7 rods and have several NRX+ rods. Here is what I have. The ones I have highlighted I would consider essential to my fishing and what I use the most.
802C JWR- 1/4oz jigs, some small swimbaits and shakey head. Love this rod for 1/4oz jigs. When I fish this rod I am using it in shallow water and in tight quarters.
853C JWR- 3/8oz jigs, Dark Sleeper and T-rigged soft plastic up to 1/2oz.
894C JWR- 1/2 - 3/4oz jigs and some soft plastic. This has become my favorite jig rod. Plenty of power and sensitivity.
895C JWR - 3/4oz and up jigs, punching and heavier flip and pitch baits. Sensitive but more power than I will ever need.
843C MBR- Swimjigs, soft plastic, topwater and just a great multipurpose rod.
904C MBR - Topwater, my favorite for football jigs, heavy soft plastic. Another great all around rod but for heavier stuff.
873C CCR - Another great all around rod. I use this for when I want to switch from jigs to spinnerbaits to even topwater. The action of this rod rest somewhere between the 843C and the 894C.
883C BJR - By far the best Jackhammer/bladed jig rod I have used. I was skeptical when I got it but fished it and now it always goes with me. It is also my favorite spinnerbait rod. Technique specific but pretty much perfect. Hate the hook keeper.
821S NRR - This is my essential finesse spinning rod. It's sensitive and throws light stuff, like neds, small drop shot and small swimbaits. Just a fun rod to fish.
872S JWR - By far my favorite spinning rod. It has more power than you would think for a 2 power rod. It has a soft and quick tip but the power from the middle down is fantastic. It is oddly different from the rating but in a good way.
803S JWR - Short dock fishing with Senkos and free rig baits. This was my first NRX spinning rod and it has never let me down.
842 SJR - Jerkbaits, drop shot, swimbaits, senkos and spybaits. It's similar to the MBR casting rods. Just a good all around rod but it's not the best at any one thing.
I am considering the 822S DSR, 902S or the 901S. I have had a chance to fish each one of these now and they sort of hold a spot in my head but don't necessarily fit a need. We will see what the bait monkey says.
