I have quite a few lightweight rods ranging from; 00 to 3 wt's.
They are a true please to fish.
I have caught a lot of large fish on them ; 7 pound carp to 18 inch rainbows.
You have to realize that they are not long distance casting rods, athough you can get some good casts in.
I have cast some large flies for bass, but you have to ajust your casting stroke to accomidate the larger flies.
One important thing to rememeber is that you need a good reel for those rods.
Lightweight rods make you feel like every fish is a brute!
I think that everybody should at least try fishing with one for a day.
Take care,
chris
