What type of water do you fish? Are they small streams or rivers, local ponds, big lakes or major rivers, or even like me, big tidal water like the Potomac River and upper chesapeake Bay. Do you fish from a boat or shore. What type of lures do you enjoy fishing? What lures would you like to fish that your current rod does not do well.
You have a nice Lews reel and a Mojo Bass series rod that works as a good all purpose rod. That is great. Tell me what model the rod is. Do you own a good spinning rod and reel combo.
I own way too much gear, but if I had to start over I would use a 3 or 4 rod strategy.
My first rod would be an all purpose spinning rod. Something like a 6'6" to 7' medium power fast action tipped rod. It would spec as a 1/8 to 3/4. I would throw all of my plastics likes worms, creature baits, crawfish etc. either weightless or as lightly weighted texas rigs on this rod. Lures like Mepps spinners, small topwaters like Pop Rs, tiny torpedos, jitterbugs etc as well as floating/ diving minnow baits like the Original Rapala minnow would be thrown on this rod. I would also throw tubes, grubs, Sencos and Ned rigs on this one.
My second rod would be a 6'6 to 7' medium power moderate action baitcaster. If you bend the top of this rod it would easily bend down past the 4th guide. This rod throws all of my treble hooked lures like RattleTraps, crankbaits, chatterbaits and spinnerbaits.
My third rod would be a 6'6" to 7'3" medium, heavy fast action rod, so it is definitely stiffer in action. This is my jig rod. I would throw any jig above 5/16 with a plastic trailer on this rod, as well as all of my plastics rigged up with a 5/16 or larger weight, so all of my texas rigs and carolina riggs and lots more,
If I was using my 4 rod approach I would drop my original spinning rod choice in favor of a two spinning rod approach. The first would be a 6'6 to 7' medium light fast action 1/16 to 5/16 rod and the second would be a 6'8 or 6'9" medium power fast action 1/8 to 5/8 rod. These two would handle all of the same baits as the first spinning rod but would handle the lighter baits better.
If the water I fished was all matted grass or lily pads then I would own one spinning rod and my 4th rod would be a big flipping, pitching, frog rod. If I fished over lots of submerged grass beds I would consider a really nice rattle trap, spinnerbait rod.
These two strategies of course requires lots of money. If I was not going to spend that or if I fished from shore then 4 rods is too much to deal with, My choice would be one good all purpose medium heavy baitcaster and one good medium spinning rod.
These combos are just tools. When I go to work with my tools I have screwdrivers, wrenches, sockets and hammers. I look at the job to determine the tool that will do it best. Look at fishing the same way. Pay lots of attention to the places you fish and what lures you want to be able to fish, that will help you decide what rod combo will fit your needs next.
