scm2, I liked your post and article. I wasn't aware of that either. A 5-10lb "swing" is significant to me. Good luck with your ROTW from Moscow(Russians invent thoroughbredski!)

In a curious afterthought to that article, if , as the article says, the weight issue results from owners not wanting their horses to carry more than 130lbs, presumably for health reasons, why are they so willing to permit drug experiments on them? raz
