Just got the 2 copies this book from Spey Bros. Top Salmon Flies vol 1 and 2.
I prefer the second volume.
But both books imo are good.
I like the fact it tells you different methods, and different times to fish the particular fly.
Its mostly from Skandi fishers, and Skandi river.
Iv actually fished with some the guys in the book, and believe, they can back up what they say. Good fishers.
If you have chance plz check these books, way in front anything Iv seen recently .
