The first endurance riding
'how to' books that were written back in 70s/80s used the classic profile for
the Appalousa as good conformation for endurance riding.
Yes a good one is: Lewis
Hollander and Patricia Ingram's Endurance riding-From Beginning to
Winning
See pages 14 and 15 where you
will see the George Pippen Ideal Appaloosa horse which is still the style that
I have been breeding for 32 years.
