i understand how hard that is , 3-4 years ago i was in a very similar situation , I had two nice stallions ...nice but not great ,...I worried about it for a long time - over a year before I made my mind up to sell them both and buy something better , it killed me to let them go , I had owned them both since they were yearlings and loved them to bits , I got the money together and bought myself a really good stallion , I know now it was the best thing I ever did , I havent looked back , my first foal crop from that boy has just been born and Im very proud of them , I just wish Id been brave enough to do it sooner
