It is a nice looking buck. Good back forks for the G2, Im going with 16" G2's. Decent G3's but not spectacular. I am thinking 8" on both the G3's and G4's.
He seems to be lacking length on the main beams, I estimate 25" beams. Conservative mass measurements at 4" each and a 22" inside spread.
I come up with right at 160" gross. Of course if I have shorted him an inch on the tine lengths that would put him closer to 170.
