Oh yeah, sorry just re-read your first post....duh.
If you are trouting, then I would definitely recommend the upper beat. There are lots of good pools - The Meadows, Top Hole Corner, a bit in between the two which holds as high a density of trout as I've ever known in a stretch of water.....nightmare to wade though.
Edwin, the keeper will be generous with his advice once you are there. If you need some really in depth info, you could try contacting my friend Patrick who guides on both beats and knows them very well.
