STX, I agree, I believe the one in the recent pics is the taller narrower buck, and not either of the wider bucks in the older pics.
He appears to be quite a bit ahead from last year this same time (fourth pic in the first post) so I was wondering if that means he will finish bigger than last year or if he just will finish earlier and be about the same? I figured him around 4.5-5.5 yo last year but was my first year on the property so I could be off. I did see him once in person last season, much bigger body compared to most of the bucks I saw, and seeing him in person really made me think he was right in that solid middle aged category, but not terribly old. He was working a scrape line during the rut and all the smaller bucks that were there deferred to him.
One of my neighbors to the south ha some deer with split tine genetics but I have yet to see anything like that on my place. Not a fan of crazy junk, but splits and some trash at the bases are both pretty dang cool looking to me.
