6-8 isnt a nice of a range to fish with, IMO.
you should get 2 rods. one for 4-6 ,then one for 8+. this way you have more headroom.
you dont necessarily need 2 reels. just use 1 reel with, and switch rods if need be.
you dont wanna be caught fishing with changing wind/weathers .. like your fishing with 4oz half day, then bAm!
tides roll in, the bite is on. but you need 10oz. and your 4-6oz rod cant cut it.
