Great guidance so far. Here's my deal after a few years honing it.
1. 7ft Heavy Baitcast - strictly pitching and dunking heavy junk.
2. 8ft Heavy Baitcast - frog(or other plastic topwaters) heavy think junk
3. 7'6 M/H Baitcast - Flipping and/or skipping plastics.
4. 6'6 M/H spin- tube, senko
5. 6'6 Med/Heavy Spin more on the heavy side- jerkabait(may want to go lighter, heavy is just my personal preference.
6. 7 ft M/H spin - topwaters
7. 6ft HEAVY (poolcue) - use for 2oz jigs busting think mats.
8. 6'3 light spin, incase the Misses wants to dropshot.
Get a couple of each (bait and spin) until you dail in what style you like to fish... this could take a while.
Above it my Bass deal, but use most the same spinning for walleye. The Heavy spin I use for rip jigging as well as jerks for eyes.
Good Luck
