Scott,
Dont mean to make this even more confusing but I was somewhat surprised with the responses myself.
For the Trophy section I have always used a 6wt with 4X and 3X. I guess I am a little rougher. laughting this over with my buddy we were talking about how easy some of those big trout where breaking our lines. Might need to more on my finesse,
I use a 4wt with 6x and 7x in the Park backcountry.
Good Luck
