HI I was wondering what I should be using on my 5'6 medium action rod. I have spinnerbaits, jigs, crankbaits, topwater lures, and alot of worms.

I usually use weightless worms on my spinning reel.

A short Med power casting rod makes a good rod for in close spinnerbait casting and topwater rod.

As mentioned above a shorter rod is great for making close, accurate casts. Without actually feeling and using the rod myself it'll be up to you to determine exactly what bait. I don't use medium action rods very often unless I'm using something with treble hooks or lighter wire hooks but, then again, I'm not using "high end" rods either.

Where a shorter rod falls short, if you will, is in situations where you're making longer casts. It's harder the make the cast, harder to set the hook well (especially with lighter actions), and harder to handle the fish.

Ultimately, however, you use what you got. Just don't expect a good hookset with a jig on a long cast.

If that is your only rod, then I suggest you save for a longer rod.

So the rod I have is bad or what?

The rod you have is "technique specific". For an "all-around" rod I would recommend

6 1/2' or 7' Medium Power/ Fast Action.
