What are you fishing for? Also, Where are you fishing, IE, Docks, the bank, a boat, along riprap at a dam? That would help us guild you more. Probably a Graphite spinning rod and reel in the 2500 class of reels.
Well right now I don't fish for anything specific. I just bait a hook, cast it out, reel in whatever I catch, and then let it go. I just fish to relax and get out of the house.
Right now I fish off the dock but I have a kayak coming.
Fiberglass rods (cost effective examples: Ugly stik, Berkley Lightning rod)
Tend to be heavier. Have a parabolic bend with a moderate action=not very sensitive, but the rod has a lot of give
excellent for topwaters, crankbaits, and other lures with treble hooks
A medium Ugly Stik is a great rod for most topwaters and crankbaits
A medium heavy Ugly Stik is good for large topwaters and large crankbaits/treble hook swimbaits.
Graphite rods (cost effective examples: Abu Garcia Vendetta Falcon Bucoo) Lighter, have a faster action at the tip and (in general) bend more at the tip.
Medium powered good for most middle water column singe hook lures--spinnerbaits, single hook topwaters and smaller single hook swimbaits
Medium heavy powered good for 1/4oz to 1/2 oz bottom contact single hook presentations--Texas Rig, smaller jigs
Heavy powered rod--good for >1/2 oz weight bottom contact presentations (heavier jigs, flipping thick cover) and also when fishing heavy grass/lily pads--ex: topwater frog
