I've had Chub from all over the isle, when fishing at the mill I like to be opposite the waterfall in amongst the tank traps taken a few in the warmer months trotting a piece of breadflake on the surface too. I've never really had much success at Thorney so I don't have any tips for there you sound like you're doing better than me anyway.
Had this Perch yesterday at the pond on a spinner
BLIMEY! Never had a fish that big from dillington, how did you retrieve the lures, whereabouts on the pond and what strength line?? Thanks
