Thanks for all the replies guys - I've gone with the Adrian Freer option as my mate is going to be fishing the same reservoirs as the author.I've read it, good book, with some useful tips, as is 'A passion for Trout' by Mick O'Farrell.
^ apologies, not much of a review, but they are both good books by real anglers who know how to fish.
I've also bought the Loch Fishers Bible but that's for me.
JY you are on my ignore list but I do unfortunately still see your posts when you're quoted, as usual nothing of substance to add it seems.
Once again thank you all for the recommendations :thumbs:
