lots of bs is talked about fishing in France.
after all you're just fishing for carp as you would at home, just hopefully bigger ones. up your line breaking strain to 15lb or so and lets say you use korda longshanks, just upgrade to longshank x's. (thicker gauge therefore stronger)
If you are not fishing at mega range your normal home kit will do just the same job as it does here (unless you fish at mega range here) and as for your hooklength, its more than likely 20lb bs or so anyway so why change.
just step up your home gear a little (line and hooks) keep the rest the same, why complicate matters.
Enjoy it and best of luck.
