Hi Jean,
Interesting question - I know as the proud owner of a Regal Remark mare, the question has kept me awake at night.
I downloaded the broodmare Sire nicking report from equineline for 2005 and it gave some insights (though the more interesting side I found was the Sires of sons side - Seattle Slew and Wild Again seem to be a nice nick)
After watching Regal Miss, and Amber Morn at hastings I am partial to Mass Market

Whats the name of your mare? My mare is A Regal Reflection - ran her retirement race Sunday at Hastings - came out of it with a check ligament
