I have a 6126 with a rio windcutter on it. I like it a lot for summer runs on the G.R. I have also used it in the salt for big cutthroats as well as on the Missouri at night swinging for big browns.
As far as a reel, a Ross CLA 4 would probably be a nice fit if that is in your price range. Redington has also come out with some nice reels lately that i have been using. The CDL 9/10 is one reel i use on my 6126. But i have been using the Rise with my latest purchase, a 5wt, and i really like this reel a lot.
good luck
