Not too bad at all. Up close, you've got Shining Spark, who is a wonderful reiner and one of the base studs in Carol Rose's breeding program Carol Rose Quarter Horses
And a little farther back, you've got some really nice cutting lines; Docs Jack Sprat, Doc Bar, Poco Bueno, Rey Jay, Docs Hotrodder, etc.
She's got some really nice older performance lines. Depending on her conformation (if it's good enough), I'd look for a good performance stud to cover her. Maybe a cutter or reiner, or even a good ranch stud.
