I have not used them myself either, what I can tell you is that I have seen Q-dogs calfs at a sale and Money Shot calfs at some sales also. I have not seen any saltydog. I was disappointed in Q-dogs calfs and they were some of the lowest selling calfs in sales around here (Wyoming) that I have went to. I have seen some pretty decend Money Shot calfs that were nice. Just from what I have seen I like Money Shot and it looks like that cow is big framed, so I think Money Shot should work well for her. That is my pick out of those 3 bulls you like.
