Hopefully they wont go wrong by mixing all of that Northern Dancer/Raise a Native/Native Dancer blood together  I'm interested in seeing the offspring's body type, although both horses are heavy on the Native Dancer blood, I believe that Medaglia Doro passed on his strong (and very nice) looks to Rachel Alexandra that is a distinct look from the Native Dancer look (more so his sons passing on the look I think).

When I first started riding, the facility where I rode had a breeding operation and their best broodmare was an own daughter of Northern Dancer, when their Quarter Horse stallion was crossed onto her the babies were always very athletic and were real lookers.

Of course looks mean nothing if you can stay sound on the track and run fast, so all three attributes would make for grand offspring.

It WILL be an interesting year, for sure : )
