I have 5 in my co-angler toolbox. Out of those 5 only 3 are "necessities". The other two are to have other techniques tied for the day.
1 - 6'6" MH Baitcaster - 15lb FC - Jigs, Spinnerbaits, Chatterbaits and a lot more
2 - 7' MM Baitcaster - 10lb FC - Treble hook lures
3 - 6'6" MH Spinning - 10lb Braid - All softplastics, light t-rig, tube fishing etc.
4 - another spinning 7' MM for a complimentary finesse (usually drop shot. Can also fish all the #3's in a pinch)
5 - 7'MH Baitcaster - 20lb FC - For those not so light moments. (Frog etc. Can also fish all the #1's in a pinch)
