My lightest rod todate is a TFO graphite 4 wt. 8 1/2 feet long. It works great on my ponds.
I'm a fan of Lefty Kreh's writings and several times in his books he has recommended a 3 wt. rod for fish, primarely trout, of less than 5 pounds. Since my gills are quite a bit less than 5 pounds I thought a 2 wt. would be appropiate.
I'm awaiting the arrival of a TFO 2 wt. 8' rod. My thinking is that it will fit nicely for gills in small, realitively clear waters. I've read on a bunch of other sites of folks using 0 to 7 wt. rods and was interested in what you guys were using.
And, just to create a little controversy, from a purely "Fishing Fun" perspective I feel that ounce for ounce my GSF and BG are fairly equal fighters. I use size 10 flies for the BG and 6 to 10 for the GSF. Both are great fun on a light, long fly rod. But not so lite or long that it would endanger the survival of the fish.
Temple Fork Outfitters 5/6 weight, 4 piece, 9 foot rod is what I use for pond fishing. Fishing in ponds, I occasionally hook into the mighty green carp or a channel catfish.
Also when in pursuit of some Boone and Crockett 'gills those guys pull plenty hard enough to warrant using a 5 weight rig. I guess I am just used to catching really big fish!!!!! Just kidding........Kind of.....Being overly confident and 10' tall is very easy to do online!
Nate, this is not a commercial but Temple Fork Outfitters [TFO] lifetime no fault breakage warrentee was a big plus in my choosing their products. I'm sure you considered it also.
I'm very satisfied with their performance, I now own three. But my fear of the occasional BIG FISH, GREEN CARP, and CHANNEL CATFISH or worst of all a large turtle handing me a bunch of broken puieces is somewhat tempered.
