I bought my stallion from Mark - and he has impeccable manners!! Mark knows his horses and is very professional in all he does, so I don't think you'd go far wrong!
Mark is very knowledgeable and very professional and a lovely bloke to deal with. I've used a few different stallions of his for years now and would always recommend him. He's helpful and approachable, I don't think you'll go far wrong with his stud.
I'm a livery on Mark's yard. Agree with all said above- he really knows his stuff and has some beautiful stallions at the moment.
Noticed on another of your threads you were looking at Canal Laura's lad- he is a lovely stallion. Magic Morris also throws stunning foals if it's a connie you're after.
