your 7′ MH is your most versatile rods and while it won’t do everything great, it can work as a rigging rod, dragging jig or plastics around, pitching and chucking swim jigs (among other things).
I’d personally ditch the 6’6″ for frogs in favor of longer stronger rod. I prefer a 7’10 or 7’11 for frogs, but you could pull double duty with a flippin stick loaded up with 50 lb braid that should definitely be added to your arsenal for punching milfoil. Assuming your fishing in the back of the boat, I’d also opt for a shorter spinning rod for skipping docks. It will give you better control for skipping into tight quarters. Obviously a 7′ will work, but give a 5’9-6’3″ a try and I’ll think you’ll quickly find it’s a better size rod for the application. While you’ll get a lot of different opinons regarding this, when it comes to dropshotting I think a 6’3″ is the perfect length for a drop shot rod. However, I ALWAYS fish braid and I rarely make more than a 10 foot flip from the boat when drop shotting so I don’t need the extra leverage of a longer rod. Add a 6’3″ spinning rod and you’ve covered 2 more bases.
On that same note, if I were going co and had no idea what we were going to be doing but knew we could fish anything from frogs to rocks to weeds to docks, I’d have along
7’10” XH frog rod
7’6″ H flippin stick
7’3″ MH rigging rod
7’0 MH general purpose
7’2″ MH crankin rod
6’8 M spinning
6’3″ M docks and dropshot
7 rods should be your absolute max for bringing into someone else’s boat. A quick conversation to get a feel for what your boater is fishing should easily allow you to pare down the selection to 5 before the tournament.
