id fish it matey the lake im on when i went on had them up to 21lb its free, quiet, and stunning i love it there but its hard and any fish be it a 15 or a 20 gives me the same greatest sense of achievement.if there was one next door with imported 40lb common carp in (cough cough) i would in no way be even tempted to look at that water its going to be really hard to replace my current water after iv had all the fish in there but im sure there someplace out there i don't know maybe penny flash but at the moment im loving my fishing and the biggest is upper 20's in there
