the thing with fishing in france is that the owner/resident bailiff (if the lake has them) will tell you who caught what, who fished where, how much bait they used etc so youve already got part of the picture in your head regarding what your fishing over bait wise etc. the owner/bailiff will help you as much as they can as they want you to catch fish, book up again next year and tell all your mates. the chances of that happening over here are pretty rare id imagine. but for me the fact that most french lakes have lots of big fish and they can eat tonnes of bait is why id take 40-50kg of boilies. my mates have fished on rainbow when the belgium angler alijn d'janau or whatever his name is was on there lol and got chatting with him and he said the biggest mistake alot of the english anglers make is their lack of bait. he said to them " you all bring 20-30kg of 18mm-20mm bolilies,, you all do the same, you need more", ok he is sponsored but he had 100kg of 10mm and my mates said he smashed it for the week they were there. and lets face it, a trip to france is not cheap and i want to make the most of it and not run out of bait half way through especially if the fish are having it big time. most lakes out there have freezers out there to keep bait frozen so what you dont use bring home and put it back in your own freezer( if you have one that is)
