If he showed up on my camera in WI I would call him a 3.5.
Is it the picture, or is his right side a lot weaker than his left?
Either way, I would have taken him and called it one hell of a year!
From what I see from you, you have some great deer on camera and have a good handle on this hunting thing, so I am sure you made the right decision and it will pay off in the end.
Best of luck!
