Good luck mate. The first week or two are often tough, not least because the fish haven't been feeding on bait. I've been for a few short predator trips but not had much of interest beyond jack pike and smallish perch.
Gearing up for the rivers myself and going to be hitting The Trent and Ribble over the first few weeks. I'm having a week on The Wye myself in September again. We did really well last year and I'm looking forward to it.
Good job you are coarse fishing the Wye mate.
The salmon fishing is bloody awful!
Give me a shout if you are Hereford way.
