I’m certainly not an expert as I seldom catch eye’s if I can help it…but…
I have weighed a number of POST spawn eyes at the 30 inch mark, they’ve weighed anywhere from just over 9 to 11 pounds. Most of them cut the 10 pound mark.
Personally speaking, if you get out frequently I would put in some more time. However I don’t believe anyone here is going to say that is not a 10 pound fish.
PS One of my first eyes when I stopped fishing for them was a 29″ tube that weighed in at just over 5 pounds.
