I would go with carp if frozen. Fresh anything will probably outfish frozen though, when it freezes a lot of the liquids like the fats freeze out of the bait so it doesn't smell the same. Plenty of ponds rivers and creeks that have sunfish that are catchable from the bank the evening night or morning before the trip.
Hooking a fish is like playing string with a cat. The exact size, shape, color of string matters less than how you wiggle it- and little cats are easier to fool than big ones. John Gierach
