Bazz, I sometimes do, it just depends how active I am. I've found that I can make good money with them as long as you've got a horse that's placing well
Grape, if you don't think you'll have the EBs by RO I would wait but if you think you can make the EBs back by RO go right ahead. It's completely up to you and how your stable is run!
Sorry, ended up talking to my sister. I could earn the ebs back pretty quick I think, without going into detail because main chat. If I get another set of mares/gelds this week I could have a complete set- one on week 4, one week 3, one 2, so on. Hm.
