Currently, I have two good rod/reels. Both are baitcaster's. Shimano Citica's. one is on a 7' Custom rod MH, The other on a 6'6 Team diawa pro bass model.

I'm buying two good spinning set-ups.

One I want a pflueger president with 8 lb test.

The other reel, I'm undecided on, Maybe The newer BPS extreme? I'm open to suggestions.

Need suggestions on rods also.

One I want to be able to fish for Crappie, Bluegill and bass. I'm leaning towards the president with 8 lb line for this.

The other just crappie and bass.

Could the president with the right rod be able to be fished with, plastic's, Cranks, spinnerbaits?

Boat, shore, open water, heavy vegetation? I'd go with 6'6 6/12 med or ml for open water and if you're dealing with a lot of vegetation I'd go to the next step up 7' 8/17 rod. I only use spinning and have no problem fishing variety of techniques and lures.

What size president ? Depending on size you may look at another line option. I don't give brand recommendations, especially not knowing the price range. What I like you may not, you may be spending more or less than me.

You are asking a lot for a rod that is light enough for Bluegills, and still heavy enough for bass.

With that said...

It looks like you are looking at a "ML" rod at most for the Crappie, Bluegill rod , and a "M" for just the Crappie and Bass. With those size rods, you be wanting a small to medium size spinning reel to match up to the rod. In my opinion, if you want to fish cranks and spinnerbaits on those rod/reel combinations, you will need to keep the size of the cranks and spinner baits on the small size. Fishing big ones will put a lot of strain on a spinning reel, and rods that size are not ideal for lures with a lot of water resistance.
