Hey John you got me looking through some old photos I had laying around and I ran across a few you might find interesting...
First is an "ugly" thayeri female that used to produce some nice babies when bred with the male below. This was taken just after she layed in '97.

and here's a different looking male (that I still use today at 12 yrs of age)

and here's the female mex-mex you asked about. Full of eggs here, this pic does NOT show the bright orange of her saddles. It appears as if they are red and they weren't as much as they were orange. She's the grandma of most of my mex-mex these days..
