Ok, am I missing the point?
Bespoke rod made in Scotland from custom mandrels and cloth - David Norwich - also have the ability to get small runs of your own blank run off.
Bespoke rod made in Scotland from custom built cane (Bamboo) - Clan Rods - will build you EXACTLY what you want..but its expensive. (also do carbon, greenheart etc)
Rod designed, manufactured, built and marketed in Scotland - Daiwa - massive range in both cost and quality.
Custom built on a "label" blank - numerous builders from small, " a dozon a year" to the likes of Alba Rods that do hundreds a year.
So what is the uniquness of it? Where is the niche? You can get Scottish built, from the ground up, rods from £100 to £10,000 already.
Not trying to be obnoxious, just trying to work out what the finished product is and what would be unique about it and therefore why would people want one?
Ben,
You mention about carbon technology etc...there is one UK blank manufacturer that can and does take on the US companies, but unfortuantly its not interested in fly rods. I would even go as far as saying that the technology this company has will feed out to the likes of the US companies as its primary role is the development of military compositse. ie, helicopter blades etc. extremely advanced stuff that they are now using in there carp and sea rods.
