I nearly put this on the trying for perch thread but thought it not relevent,I'm going to try for big perch in the next few weeks on a stretch of river near to me,they get quite a few three plusses,I had a 3-5 myself the one time I've fished it,the problem is crayfish and at this time of year they will be very active,I've thought about feeding lobworms cut in three plus maggots,but then,rather than lay on as i normally would,I'm thinking of casting to mid-river and letting it swing round,perhaps allowing the float to hold for 4-5 minutes before recasting,this not allowing the bait to be stationary for too long,possibly fishing slightly under depth,your views please?
