I learned a couple years ago that body size gets my heart racing the same way a booner Buck would, regardless of antler size. Throw in some good mass on the horns and 5.5 years+ and that’s a true monster buck in my book.
Small buck would be a young, small bodied and antler deer, and a good buck/shooter buck for me could acceptably be medium body size paired with a good rack(no way to define this as it would just have to be big enough/wide/heavy/ or character to excite me).
All this to say that I’d be happier with a 300lb+ old brute with a 150” rack than a young, spindly good genes 180” deer. But golly do I love em all
