Most LMB reach a maximum weight then start to decline as their health fades. This bass may be at her prime condition now and may weigh a pound more during the late pre spawn period next year.

A couple of years ago I caught a 28" LM that only weighed a little over 8 lbs. She had a bad eye and was in poor shape. She would have been way over 10 a few years before.

Congrats! You must have caught her in Maine!   Just curious.....what were you using? How deep was the water? I won't ask you where, but you can tell me if you really want to  

Huh!  This morning I woke up with a piece of scalp missing!  Do you suppose some aliens were trying to determine my age?  I don't want to know why my butt hurts!

I think you have been hanging out at the wrong places
