My current love in light rods is the Bass pro Micro-Lite series. For your needs I would select the spin-fly in the longest which I think is the 8 1/2' It has the large spinning guides you need. Couple it with any quality reel but be sure you have a large spool dia. Tiny micro reels, in my opinion, just don't cut it when casting these super light jigs. Ad a dab of graphite to the drag of any reel.
Your selection of line would work out fine, but I would prefer 4lb .Trilene XL mono. In fact, my next venture in open stump free water will be with Trilene XL #2 lb. test, and is not as insane as it sounds. The long rod makes light line much more forgiving.Your Fireline would allow you to pull off wood if necessary.
One of the popular magazines (In Fisherman???)done an article on a fella that spin fishes with a custom 3 wt. rod blank fitted with spinning guides. He uses 2 lb. Trilene XL on a large spool reel with a good drag, and casts jigs and flies as small as 1/100 oz. He successfully lands big "bull" gills and big crappie.
Well, got to rambling here but please realize that as you venture into this light jig-fly fishing on light tackle, you are going to have a ton of fun. Don't be at all supprised if the fish get a little larger also. :D :D Mike
