The back cover: Personally, faced with the diversity of products available on the shelves of my favorite fishing store, I am a little lost. Needless to say, when I had to buy my first pack of boilies, I was even more disoriented. All in all, I don't feel more informed now than I was back then; I have simply learned to live with the mystery surrounding this mysterious ball of paste that we all use and that sometimes smiles at us and disappoints us the rest of the time. This was until one key day when I made the decision to no longer live in ignorance of what I was buying and to spend colossal sums of money on baits that I believed in without deep convictions. Since that day, with the entire STAPIO team, I have set myself the goal of understanding this bait with a view to using it in the best possible way to optimize my fishing and invest my euros directly in a bait that multiplies my chances of catching fish. Since that day, I have discovered a wealth of information about this bait that I reveal in this book. It is nearly 20,000 scientific data, hours of reflection, days of work and liters of distilled brain juice to set up this project to understand our favorite bait. The STAPIO team has worked tirelessly to offer you nearly 200 pages of new discoveries, in-depth research as well as a hundred product sheets to allow enthusiasts and curious carp anglers to choose the bait that suits their needs! Hold on tight because what is in this book will not leave you unmoved! We guarantee you a new perspective on boilies and some great sessions to come if you follow your brain... We look forward to seeing you at the water's edge. 16x24cm format (like the 2021 Boilie Guide)
