India's been improving its stock for decades, and I'm afraid you'd be very wrong about your perception of them, Roddy O. Perhaps you haven't been to a meeting at the Bombay/Mumbai Turf Club? You ought to go, then - it's a beautiful, traditional place, very well-supported by sporting Indians of all castes, and providing as many facilities for the horses as you'd expect at a decent course here. I didn't have an opportunity to visit their studs when I was in India, as I was on business, but you'll probably have noticed some of their advertisements in Owner & Breeder magazine from time to time. They're generally a lighter-framed but very sound animal, like the South African-breds, and I'd urge you to shrug off your bias until you've had a look around for yourself. You'll be very pleasantly surprised.
You could equally say, imagine finishing up in Turkey, Saudi Arabia, Greece, or Uzbekistan - but unless you've been to those countries and seen the facilities for yourself, I'd hold off until you do.
South Africa has been breeding from British stock for many decades - back to the 1920s, in fact. You can look back through any amount of their runners in the 1960s and see the crosses to Hyperion, Nearco, etc. and their descendants.
