I'm thinking that 1 through 5 have a face shape that fits better with Greenside. Individual (6,7) appears different, but it could also be because it was a lot younger (presumably, it was smaller). Using both my Peterson and the Fish of Tennessee, and I'm still having trouble getting some solid field marks other than ones that I would only be able to determine in hand.
Thanks for the help! I've learned so much on this forum and have been really excited to ID a lot of fish in the water, such a rewarding feeling!
