I like heavier rods than most because I have an easier time casting poppers and weighted flies with them, and I think it's more fun to play fish on a stiffer rod. I'd suggest a 9' 6wt or 7wt. Most people will suggest lighter rods, though.

Look through the "Panfish" forum for similar threads. Almost all the fly fishing threads are in that forum. This question has come up a lot before.
