I think your being generous on all of them. g1's more like 4.5-5 his g3's are alot longer than a inch morethan his g2's more like 2 or more and his spread is barely outside his ears so I would say 15-16 spread. With all this being said that is at least 6 inches smaller than you said wich put him in the 150"s. His body makes his rack look bigger than it is.
