Why do you want to start with a specialty rod? A ten foot #4 is for the most part a lake rod. I would advise getting a 9' #4, if you want a #4. Personally I would suggest getting a 9' #5 rod, it is the best rod for all around trout fishing. If the wind kicks up, this does happen sometimes in Montana, and the Yakima in the spring and summer is like a wind tunnel, A #4 rod can't handle the wind.
Check out the FR1085,FR1085-4 or the FR1084GL3 these are all very nice tapers. Stay away from the 1024-4GL3, it is a piece of crap. Also the Adventure series rods are pretty nice.
