Dr. Dave, yes, shape = football (or more like a rugby ball).
I have a few 21" and maybe 22" LMB in my Pennsylvania pond, and I would say they are five pounds, maybe six. However, I don't feel that they are undernourished or unhealthy in any way. But to be less than half of what these TX bass are as far as weight, and within 85-90% of overall length. Crazy.
Tunas, just Tunas are what these ShareLunker bass are.
