Kai, you have excellent points. I hope I didn't discourage anyone from fishing bamboo. They are plenty durable, as are graphite rods. The difference is the price. I'm only a few bourbons away from calming down after I bust a graphite stick. A bamboo break, and I'm looking at a week long binge and being kicked out of the house.
They are beautiful tools and the best are truly art at it's finest. The only issue I have is that the one I owned and broke was worth close to twice what my truck is worth.
Oh, I almost forgot - if you ever head up to the Yellowstone region, I'll row you down any river you would like for a few casts on any of your sticks!
