Dude, you had to bust out with the hard question. Well, for weight I would say February thru March definitely. Fun? You didn't ask that. Summer is great catchin' lots of dinks. I would say the Summer months because I love catchin' lots of fish. I am not so hung up on big fish. Don't get me wrong, I fish the Winter months very seriously because of the BIGFISH factor. All of my biggest fish 10 pounds and up (10.1) yeah,yeah,yeah, I know thats small to many folks, were caught during the Winter months. I am still working on da next world record. Hugs & kisses, James.
