I have several rods in the 6ft 8in to 6ft 10in. range with 8-1 gear ratio reels on them. I use them for finesse fishing, weightless senko's, and flukes. Nothing "funky" about that set up. It works just fine.
You use a 6’8”-6’-10” med/hvy rod for finesse fishing?
Yes they are M/H with a soft tip and they work very well, and all of them are bait casters. You don't need to limit finesse fishing to spinning tackle only.
Also a M/H rod depends a lot on the manufacturer, they are all different in their ratings and actions.
