Re: Boo Porn.....
Each blank is tapered (the rod above is a Payne taper) and plained to behave a certain way within loose peramiters.
A rod builder friend from Idaho convinced me to try this china blank he said was great for the beginner rod builder. This being my first project I jumped at it. So I purchased the blank from him, but do a google search on bamboo blanks and you will be surprised at how many are available.
