Although it's tough to tell from few pics never mind one I also don't think it will be 200" I do think it will gross in the high 170's low 180's
here's what I came up with.
24" beam 4" g1 5" g2 12" g3 11"g4 5"g5 16" mass
and 18" spread brings it to 172
add in the longer tine and beam length 9" 181"
I'll also say this I've scored a few bucks that were built like this and they were deceptively bigger than they looked even holding them.
The two bucks that come to mind like that were taken by guys from this site. They were 130" frame bucks that due to deceptive mass...long sweeping beams several long tines racked up inches quicker than you would guess.
