Horton Church Lake produced two fish for almost 80lb from two different swims for Matthew Stone.
Two mirrors of 37lb 14oz and 41lb 10oz fell during a session at the historic Berkshire venue.
Matthew said: “I turned up at on Wednesday morning and had a good walk round the lake a few times before I found something of interest. After a few casts about with a lead I found two nice patches at about 70 yards.
“The following morning my right-hand rod ripped off and a strange fight followed. I thought I had hooked a stocky at first but as it came closer it went wild and it must have done a 40-yard run. After a 10-minute battle I slipped the net under a 37lb 14oz mirror.
Matthew added: “The swim went dead after that so on Friday morning I moved and set about putting the same tactics into play in another area, but all was dead and on waking up on Sunday morning I was thinking about moving once more when one of my rods let out a one-toner.
“This fight was very different – very deep and slow, and I knew I had a big fish on. After a nervy battle I slipped the net under a large mirror and looked in the net to see a real Church lump. It spun the scales round to 41lb 10oz, beating my previous pb by just over a pound.
“To say I was buzzing is an understatement, and i still have a whole year to bag a few more!”
Matthew fished hinged stiff rigs and baited with Mad Baits Wicked Whites pop-ups over Nutz freebies.
