These are both nice bucks but I'm having a hard time believing that first buck is a 150 buck, there is no mass, width or depth in the forks. It is a very tall narrow rack but maybe! It can't be over a 22 inch spread.
The second buck, definitely nothing wrong with that one, very nice, but again I find it hard that it is a 190 buck, it does have some width and height, but the depth on the forks are a little weak.
My guess, first buck=140-145
second buck=180
