A cow is in the eye of the beholder.
I guess I think in terms of quality. I seem to have caught a lot of hot 25 to30" fish this year that I consider high quality. Another factor affecting quality (IMO) is where a fish is caught. A 20- 30# striper caught where it needs to run a 100 yards to get to water over 3 or 4 feet deep is a memorable fish.
