I have an Impressive bred (n/n) mare that is also OLWS (frame overo). I LOVE the impressive lines - they are versatile, beautiful headed, and athletic as a rule. Daisy is a great example of the Impressive cross with a Superior WP Stud - she has won several grands in halter competition, got her Register of Merit in 4 shows in NA trail, and can do a big lofty trot for HUS but can also be slow and deep for western. She has points in Halter, WP, HUS, Trail, the eq classes and even a few barrel racing points.
I am extremely excited to see what she produces.
I am breeding her to a n/n son of Vital Signs Are Good - VS Code Blue. Vital Signs are Good is considered by many to be the greatest show mare that has ever lived, winning 11 World Championships and over 30 Congress Championships, as well as having $267,000. Lifetime earnings recorded. Her offspring have won over $500,000. In lifetime earnings and too many titles to list.
Vital Signs Are Good is N/H. And I have to admit, she muddies the right and wrong of breeding these horses for me personally. She has produced (thanks to embryo transfer) many n/n horses that are passing on her incredible talent - redefining pleasure horses in the AQHA and APHA world.
So because someone saw her talent and bred her despite her n/h status, we have studs like VS Flatline, VS Code Red, and VS Code Blue - all n/n Quarter horse studs that have extensive show records and produce fantastic riders. She has also produced n/h studs that have died - so the risk is still there.
I have owned a n/h horse in the past, and would not choose to own one again, but there are those that do, and are succesful.
Me personally, the frame overo pattern is beautiful and is not in my eyes a defect - I know not to breed her to another OLWS carrier so she will never produce a lethal white. It is a non issue in my book. I am just hopeful that in 2015 I'll have a little red roan frame overo filly out of some really amazing horses.
