hi mike
very rarely use wet style on a river these days; wouldn't be a first choice tactic. Sometimes after working up a stretch, I might walk/work back downstream sweeping a pair of wets just for fun. It can be a very relaxing way to fish, quite enjoyable for the sake of flicking some flies across the stream with no particular ambition.
Or some days, if the wind is just a complete (downstream) pig, it can be a way to fish without complete frustration.
Did pull some nice trout from a flooded Assynt stream with a couple of wets, it was pleasingly productive!
And wets will always have a place for loch fishing
