Well done Cakey, fished the same area a number of times when I lived at Enfield Lock. Saw probably my biggest Perch just a bit south of that. Went for a walk one Sunday morning when a match was on. Talking to one of the anglers who hit a small Roach, on bringing it in it was hit by a very large Perch. The Perch eventually let go but not before he got it to the surface and we had a good look at it.
