While the stallion isn't my cup of tea, that is really just a personal preference. It's not what I like, but we all have our likes and dislikes.
The thing that bothers me is not the stud. Looking at the mares on the website, almost all of them are HYPP N/H and many are listed as in foal to Elvis. Yes, he's N/N, but I personally do not agree with breeding knowing the potential posed to the resulting foals. Again, this is just my personal opinion, but I would not want to support that type of breeder. If I have misread or am misinformed, please correct me.
