The less often you fish a body of water, the easier the fish are to catch; Cody's Law.
When people fly into wild remote Canadian lakes, they can catch fish on can openers with hooks!. Remove numerous fish, give the lake steady fishing pressure and fish become difficult to catch and the catch rate per hour and the average size of fish caught decreases dramatically.
Zett's definately has a reputation but I'm not sure I would call it excellent.
