Query: A carp fisherman's review

Having purchased the book over a year ago and being a carp fisherman for over three years I found that the advice on bait application and overall fishing strategies invaluable, it has a given me a real insight into getting closer to understanding the carps mind. The book has given me not only extensive knowledge, but a improvement in results, both on and off the bank, a great read.
