We forget the basics sometimes.
Anyone that highly prefers British cattle are not going to like any exotics. Depth/capacity isn't the strength of exotic cattle, its their muscle. Within the Charolais breed, Firewater is a real good bull - both for show and for female production. Within the Charolais breed, Firewater (or any other "collected" bull) is more than adequate on pretty much every trait. The vast majority of bulls running around in any commercial pasture - of any breed - really aren't even in the conversation quality wise. As tough as almost any show is anywhere in the country, any bull that is siring winners consistently is going to good, regardless of the breed.
Anyone that really prefers British cattle - whatever breed - aren't going to think most exotic cattle are deep enough. Capacity, milk, and ability to grade is their trademark.
I'm guilty of it too, but we make way too many judgements off of photos. The more I'm out and about and see cattle in person that I've seen photos of prior, the less use I think photos are. I'll never say never, but I'll have a real hard time buying an animal I haven't laid eyes on. As far as picking bulls for AI, I make my judgements on calves I've seen. I'm very certain you really have no idea what a bull's offspring will look like based off of his baby photo, and probably off of a video or mature picture. It's hard enough to guess when you see them in person.
