I'd be up for this. would like to have a go with a fly rod too maybe
like the idea of the venues as mentioned above as i have never fished them before for sea trout
all i can say is that the entrances to estuaries or rivers can be best - especially at low tide when fish are congregated in less water. the fish will move in and out of an estuary with the tide, they try to expend as little energy as possible (swim against as little current as necessary) and so they literally move with the moving water. so at low water the fish, in theory, should be near the mouth of the estuary.
as a result, and from past experiences, fish are often caught at the mouths of estuaries as the running (draining) water from an estuary starts to slacken approaching low water, stops and turns, and then starts to move back in again.
otherwise, if not fishing the mouth of an estuary, then its a matter of working shorelines, looking for sporting (jumping) sea trout, and having a chuck!

would agree too though - fishing for s.trout in March/April can see a lot of fish just returning from spawning. they can be in poor condition (spent / half-mended) and may be (too?) easily caught because they are starving. they can also taste like crap in this state too..
either way
