Nice lookin deer my friend! I think I'd have him on my wall..! Here's my guess...
20" main beams x2
2" guards x2
15" G2s x2
8" G3s x2
9" G4s x2
18" spread
30" mass
And with that you have a 156" buck!!! I've got his sheds in my basement. LOL Not really, but very close... G3s stick out like yours does, and he's pretty tall like yours... Beautiful buck!!!
