Re: looking for recomendations on a spey set up

Yes I think if you can only have one two hand setup it should be the 14'-9wt. I believe it to be the most versatile size. If one's primary river is the Clearwater in Idaho this is the perfect size.
As to the line, any head length that turns your crank will work. A short head spey line from your favorite line company will work as good as anything. If you can get the color change to the rod tip you are casting far enough. A multi tip will give the angler more versatility but on the Clearwater a floater will work well until the water gets below 38 degrees.
And while no one has ask, and again for the Clearwater a leader as long as the rod with a 10# tippet works well. Also 100yds of 30# backing is usually more then enough.
I do agree take some test drives. Any shop that has your best interest at heart will have some kind of test drive arrangements.
