I've used it in both, saltwater and freshwater environments. Its survived the kayak environment catching smallmouth bass, largemouth bass, white bass, redfish, grass carp, gar, catfish, and some descent sized trout.
It isn't a specialty set-up, it's varied enough to get the job done for most any angler and modest in price. At $159, it's not going to win a beauty contest...but it flat out works.
The tip is a little stiff and it needs about 15' of line out to really load. But that also helps set the hook into big tough mouthed fish. The drag isn't great for stopping big reds but it's delicate enough to not snap off a big trout. The combo requires some attention after a salt trip. Some noticeable corrosion happens if not cleaned and allowed to dry completely. It's not a true hardcore salt set-up by any means, but it's not advertised as such. Orvis, "An 8 Wt. affordable fly rod perfect as a first saltwater outfit or backup travel rod".
I'm 6 hours from salt and my day-to-day targets reside in freshwater, so I'm not complaining. It has served me very well. As evident by the 3 spools I have filled with, floating line, sink tip, and I'm planning on getting a full sink for heavy flow and deep water applications.
The only drawback that I can see is, it doesn't come with the usual Orvis warranty. It's not warrantied ($159 gets you, fly line, rod, reel, leader, and a case - understandable) and that concerns me, since I tend to break stuff. We'll see how long I can keep it in the 4 pieces it arrived in.
If great performance and diversity, at an affordable price, are what you're looking for in a combo, you won't be disappointed. Another fine product from Orvis.
