Hi
In the United States there is Loomis and others also you can buy blanks and build a Trout Spey.

Please don't forget, you will require a special line also for the arrangment, something like the Airflo Plus 40 type.

Kind regards.

ps, myself I would go directly to Mr Mieser and get totally honest answers and direction from him Here you will be dealing directly with the designer and fisher and be able access his knowldge, unlike some salesman in a retail shop.

You may have noticed,
"Fast/Medium Fast Progressive "
In the World of Doubles, this term is very different to what most people understand, all because most people come from a understand of those little single handed rods.
