What Ron said.

I think weight is over rated. First, almost nobody will stand in the stream and cast for several hours at a stretch. You have to pee. You have to land fish. You have to release them. You stop for lunch. If an ounce is going to ruin your day fishing, you are a weak son indeed! The differences are so minimal that it my opinion that most of the hype over weight is in a person't head, not so much in the arm.

Balance the rod so the grip is the center of gravity or pivot point for the rod with reel mounted and full of line and it will be much smoother to use and less work.

If weight was the end all, nobody would ever fish a bamboo rod over even the least expensive graphite blank.
