@Fancy I don't see why not its your horse and it's just a recommendation, but I would look up some studs before you breed. Want me to send you some links of cheap warmblood stud?
I have entered a good few horses into member shows over the past week but absolutely nothing is showing on the stable page for showing results nor does it say I've entered any at all though I know I've chucked some into mostly dressage shows?
SSS can be good too, it just takes them longer to be 'in the green'- or making you money. This guy is one of the few that's actually netting me something right now -HEE Click-
Specifically for showing, I think a lot of people go for E geldings. They train pretty quick, but don't level up as fast as a W. So I have a lot of PEP/EPS/APE geldings for example.
