There does not seem to be a lot of interest on this site regarding bamboo fly rods; this is after-all, a shooting forum. A Little search on Google regarding bamboo fly rods, should return more than enough information on what you're looking for.
A long time ago, I was a fan of bamboo fly rods and bought an Orvis Battenkill, 7'/7'-3 fly rod. I still have it and only fished it a couple of times. It has a fairly soft action compared to the carbon fiber rods available today and may not be the the best material available from the standpoint of casting ability.
It is however, a work of beauty, something to truly behold and one of the finest things that I have ever owned made by the hands of man. My old fly reels are in the same category, they haven't caught many fish but they are beautiful mechanical marvels and a delight unto themselves.
Fly-fishing isn't just about catching fish, it's a mindset about how we interact with nature; a special aesthetic regarding the outdoors.
The best expression of this principle was one long sentence written by John Voelker, who, in the pen name of Robert Traver, wrote the
Testament of a Fisherman:
Testament of a Fisherman
I fish because I love to; because I love the environs where trout are found, which are invariably beautiful, and hate the environs where crowds of people are found, which are invariably ugly; because of all the television commercials, cocktail parties, and assorted social posturing I thus escape; because, in a world where most men seem to spend their lives doing things they hate, my fishing is at once an endless source of delight and an act of small rebellion; because trout do not lie or cheat and cannot be bought or bribed or impressed by power, but respond only to quietude and humility and endless patience; because I suspect that men are going along this way for the last time, and I for one don't want to waste the trip; because mercifully there are no telephones on trout waters; because only in the woods can I find solitude without loneliness; because bourbon out of an old tin cup always tastes better out there; because maybe one day I will catch a mermaid; and, finally, not because I regard fishing as being so terribly important but because I suspect that so many of the other concerns of men are equally unimportant - and not nearly so much fun.

John Voelker died several years ago. He was a Michigan native like me and loved Trout fishing, especially in the Upper Peninsula, whose streams he fished and haunted until he died.
To this day, I raise a toast to him each time I cast a line upon the water. Drinking good bourbon is the least I can do in his memory.
