mmmm, this is a good, and interesting question.

I have caught several for sure in the 5's, weighed them, etc. I did get one that I believe was in the 6 and a half range, it was spawning with an 8lb female. I didn't want to hook him, so when I brought him in, I released him right away without a weight. It would have been nice to get a weight on that one because it was a for sure male bass, and it was exceptionally large.

My inclination is to doubt claims of 10lb male bass. I have read Andy's comments on this several times but still feel very skeptical. I think Andy got one that he said was an 11lb male at the Delta. If I remember, he got it one day and a client got it again a few weeks later. Don't know if they saw it on a bed or not. Would be curious to hear the outcome of your research Greg.
