I fish a small stream for little wild brownies (although a few are quite big - 2lb), and later in the year all you need is match whatever's hatching and fish dries. However, in April they don't like to rise, and so the choice is traditional wets or nymphs.
I've never done very well with wets fished down and across - just a couple of pulls which I've missed. Last year I perservered with the upstream nymph (after some good advice on here to add a couple of small split shot to get the fly down through the fast water) and eventually (kind of!) got the hang of it, and did catch a few trout - and chub - on that, which was very satisfying.
So, first question - when would you choose a traditional wet over a nymph, and why? And which flies (wets and nymphs) would be a good early season choice?
How long is a piece of string and what colour is it?
You'll probably get as many different answers to that as there are fly patterns!
I try and watch the fish if the water is clear enough. There may well be good hatches but, as you say nothing may be rising to them. I observed a few fish the other day, wild brownies in 1'-3' of water. They were all taking food just off the bottom. This was however at about midday.
Choice of wet or nymph would initially depend on the state of the water. If it's clear and I can see the fish and they are holding station I would start by casting to them upstream with a nymph, especially if they are targeting food rolling/swimming down with the current. If the water is not as clear or I cannot see the fish, or they seem to be darting about I would generally use a wet and cast either upstream or upstream and across in shallow water. with a tendancy to fish across/across and down if the water was slow.
My first option would be a lightly weighted nymph cast upstream. If the fish are at the head of a pool I cast a shaky line well upstream then strip the line in quickly as it comes back to me. This allows the nymph to overtake the line and drop low in the water. As it comes into the pool the undertow drags it down to the level of the fish. Nymphs that I generally use at this time of the year are Pheasant tail and Blue Winged Olive. Shrimp copies can be good as well. If the fish are taking food midwater I would use an unweighted nymph, if just under the surface, again an unweighted nymph with a greased leader.
I tend to fish wet if I am not sure where the fish are or they are more active. Frequently a team of two can produce with a bushier fly as a bob fly (top dropper, nearest the fly line) and a wet fly on the point (end of the leader). On my local river I typically use a cocch-y-bondu bob and partridge and orange point. Klinkhammers can be useful here as a bob fly and a combination of bob fly and nymph can be interesting as well!
I tend to find that sparsely dressed flies kill better early on in my water but experiment! Evening fishing can be well worth the effort at this time of year especially if the weather has been warm during the day. A good evening hatch will often get the fish in a suicidal frenzy for about 30-40 minutes just as it's getting too dark to see. Small Klinkhammers can come into their own here, they sit just through the water surface and
you can see the tuft better!
I use indicator putty, especially on rippled water and when the light is fading when nymphing and I frequently use a very short leader of 4'-5'.
Hook sizes are another issue. I spent about 45 minutes last spring trying to hook a wild brown on the Irthon under an alder tree. It was taking medium sized green naturals. It repeatedly took but rejected my (dry) Greenwells. I changed sizes until I eventually took him on a size 20!
Here he is all 1lb of him!

Tight lines.
An update! Just been down to the river with the dog, a mixed hatch and fish bulging and taking surface flies so I'm off this evening for some sub-surface nymphing!
