Re: Neewbie looking for Rod/Reel advice
I think that FrankB2 has a good suggestion. Check out the new Sage Flight rod. Unless you are doing mostly dry fly fishing I think a 5wt would be a good choice for you.
As to the XP, even though it is a fast rod they are equipping it with the RIO Grand line. The 1/2 over weight line should cast well on the XP. I don't know anything about the Watershed reel.
