A:
That would depend upon how much you want to spend, what rod action you want/like, and what fish species you fish for.
I'm a retired engineer, love the Lamson Litespeed & ULA-SL reels for looks & engineering. I just bought a St. Croix Legend Ultra 9 ft., 6 wt for bass & panfishing, think St Croix rods are an excellent value. Sage 4200/4500 series reels have good engineering too. Sage/Winston/Orvis rods can be costly.
I also have a 1979 Fenwick 8 ft - 6 wt that is very slow action vs the St Croix that is med-fast. Both are great rods, just do things a bit differently. Each to his own.
