I have a project in mind this winter that would consider a similar approach that Chris thought about.
Why? I found most blanks in the size I was looking for 10/11 or 11/12 11-12 footers were $400 or over.Perhaps I have been spending too much time on american web sites instead of looking to the UK where the long rods are the norm.
I found a 10/11 13ft Pacific Bay for $150. By removing a foot or so could alter the action for the better for some.
While likely an inferior blank for a low budget rod it could get you an acceptable rod VS none if you don't have the cash for a quality finished rod.
Just kicking it around while I continue to look at blanks
