Just wanted to post an update. After yet more debate about the pros and cons, I have decided to go for it. My mare I'm just starting to get in shape for the endurance season, although we will only be doing 25 milers. She will be bred this summer for a 2014 anglo foal after being cleared by the vet. Here are a few pictures of the prospective sire, 'Luxembourg'. One of the most even tempered studs I've ever seen.
