As a descendant of Mumtaz Mahal, Rock Hero is a member of one of the world's most prominent families.
And the influence of Mumtaz Mahal is close up, that legendary matriarch being his seventh dam with his sixth dam being the great Nasrullah's dam Mumtaz Begum whilst his fifth dam Rivaz is the third dam of Kalamoun.
Rock Hero boasts multiple Mumtaz Mahal strains - Mahmoud, Migoli and Nasrullah as well as several descendants of Mumtaz Mahal's equally as influential dam Lady Josephine - Fair Trial, Tudor Minstrel and Aristophanes.
It is simply a case of the more the better with this family and with this in mind mares carrying strains of other Mumtaz Mahal/Lady Josephine descendants are great matches for him.
Strains of Kenmare, a stallion who stood with outstanding success in Australia - with a number of good sire sons - are of particular interest as he provides for a rare opportunity to line-breed to Rivaz.
A prolific broodmare represented by nine winners including the Gr.1 gallopers Palariva and Spicy Living, she is the third dam of Kenmare's sire Kalamoun.
Kenmare also boasts multiple Mumtaz Mahal and Lady Josephine strains.
And there are further strains of Kalamoun around, namely Kala Dancer and Jeune. Meanwhile Rivaz is also the fourth dam of Adraan who sadly stood for just one season but did make a significant impact.
Eight Carat is another descendant of Mumtaz Mahal and she is easily found in the local broodmare population... Octagonal, Commands, Danewin, Kaapstad, Special Bond, Bramshaw, Zed, Viking Ruler, Kempinsky, Court Of Jewels, Dangerous, Viscount, De Beers and Don Eduardo.
Other stallions who descend from Mumtaz Mahal and Lady Josephine include Mossman, Nassipour, North Reef, Bao Lack, Kreisler, Famous Star, Golden Snake, Nediym, Eire, Telesto, Centre Stalls, Kbenjar, Savoire Vivre, Aussie Rules, Ladoni, Nediym and Shovhog.
Rock Hero is bred on the same Fastnet Rock/Sadler's Wells cross as the Group One filly First Seal and eight other stakes winners. Sadler's Wells excels when coupled with his close relations Nureyev, Fairy King and Thatching - strains of whom are all easily found in Australian mares.
Rock Hero's second dam sire Diesis is a full brother to another topliner in Kris, strains of whom will provide for a cross of the excellent broodmare Doubly Sure. Another of that mare's sons in Keen stood in Victoria.
Fastnet Rock crosses nicely with Storm Cat, siring six stakes winners (including the Gr.1 winners Irish Lights and Foxwedge) out of mares carrying a strain. Storm Cat's second dam Crimson Saint is the dam of Fastnet Rock's dam sire Royal Academy so the success of this cross is no surprise.
Another mare of interest in Rock Hero's pedigree is Galileo's grandam Allegretta, also dam of King's Best who stood in Australia. Early days for this cross but so far two sons of Galileo have sired stakes placed winners out of King's Best mares.
Rock Hero's grandam Dragoncello is a granddaughter of Sharpen Up, son of Atan whose dam Mixed Marriage is a proven line-breeding subject - and she is also third dam of Gone West and second dam of Known Fact.
Fastnet Rock's dam is a granddaughter of the legendary Nijinsky II who crosses extremely well with his 3/4 brother The Minstrel, the Canadian Oaks heroine Flaming Page duplicated.
Another great mare to duplicate is the Kentucky Oaks winner Lalun, dam of Sadler's Wells' dam sire Bold Reason who crosses exceptionally well with his half-brother Never Bend, Strains of Gulch are desirable with that stallion boasting a rare strain of Rasper II to whose dam Red Sunset Rock Hero is already line-bred via Better Honey and Crepello.
Stakes winning successful broodmare Relance, whose Group One son Reliance appears in Dragoncello's pedigree, is also worth line-breeding to - look for strains of her sons Match and Relko.
Fastnet Rock boasts a good record when the mighty Sir Tristram is duplicated - six of his stakes winners line-bred to him including the Gr.1 winners Atlantic Jewel, Mosheen, Planet Rock, Rock N Pop and Rock Classic.
The influence of the prolific Natalma/Almahmoud family of which Danehill and Northern Dancer members is also worth tapping into via strains of Halo and Machiavellian.
More Than Ready mares are suitable with this in mind - especially as his sire Southern Halo hails from the same family as Galileo's dam sire Miswaki.
Rock Hero boasts three strains of Northern Dancer - Danzig, Nijinsky II and Sadler's Wells. Judging by Fastnet Rock's success with further Northern Dancer lines it is also worth seeking strains of Nureyev with Fastnet Rock siring 13 stakes winners on this cross.
He has also fared well with Nijinsky II, Storm Bird, Lyphard, Secreto, Night Shift and Grand Chaudiere (via Snippets). And his strike rate with a Danzig cross is also very good (61.1%; ten stakes winners).
Fastnet Rock has excelled when Danehill's second dam sire Buckpasser is duplicated - this cross boasting an outstanding 71.3% winners-to-runners strike rate producing 19 stakes winners.
Biscay is another worthy line-breeding subject with Fastnet Rock siring seven stakes winners with a duplication. He has also fared well with a Twig Moss cross (16 winners from 21 runners; three stakes winners) and has crossed nicely with Blushing Groom (ten stakes winners).
Fastnet Rock has fared particularly well with daughters of Al Hareb, Bite The Bullet, Distorted Humor, Fusaichi Pegasus, Giant's Causeway, Hennessy, Last Tycoon, More Than Ready, Peintre Celebre, Snippets, Stravinsky, Woodman and Zabeel.
