Really, now that you're about to move to North America, I don't think that there is a limitation on what breed to get. Perhaps it might be more difficult
to find what you've been riding, but I'm pretty sure that SOMEBODY in the US or Canada is probably breeding it, if you're willing to drive miles or pay for shipping. Just use the Net to search, and polish up your patience. =b
RE: gaited horses, you should try riding a gaited horse. I understand that the ecliptic spring which made buggies popular in the 19th century saw the end of many European gaited breeds. Here, the roads were not as good, the demand was higher, and the numbers of gaited horses grew, as well as in South America. Gaited horses naturally perform a rhythmic 4-beat gait at the speed
of a trot. The most comfortable ones are very smooth
, and owners love to display this by drinking a Coke (or other beverages) while they ride their horse's Running Walk, or Amble or Foxtrot, or the others (memory of the other names escapes me...) If you are most comfortable on a Tall gaited horse, then you would be most comfortable with Tennessee Walking Horses bc they were bred down from a Canadian Percheron line. Both my TWH, "Merry Boy's Hart", (2004, RIP) and my KMH were/are 16'2hh or over and my 6yo gelding is big boned with substantial hooves.
There are tall Missouri Fox Trotters, but most other gaited breeds are on bred to be on the small side. =(
BTW, I've owned several 1/2-TWH'ers and EVERY ONE OF THEM gaited. IMO the genetics for TWH's is pretty strong. Be warned however, with TWH's, they have 2 additional gaits:
(1) the pace
(2) the broken washing machine. TRUE, but ROFL, anyway!
