I know this is an old thread but thought I would help if I could. Ive heavily fished the Nene from Fitzwilliam Bridge to Orton for over 50 years now. It depends what youre after. Ive had massive bream nets over the bridge at the other barge, Fish right on the end of it. I night fish 90% of the time. For bream I use a night float,6lb line,size 10 hook,big chunk of flake,quite close in maybe 12 foot out not far off the tip of barge. They hoover up groundbait so once feeding give them some. Carp often shoal up with them. I had a night 2 years back when I had 12 fish over 10lb and the biggest was 14lb5oz. Amazing night but you often get 10lb+ there.
You can also get carp from same spot. Casting to far bank tho theres often guys carping there tho. Largest Ive had is 27lb on boilies.
