If you mean Station bred as in the type of horse bred in New Zealand, then yes they can make good jumpers. They may be limited in how high they can jump due to their stock horse conformation, but they should make good lower to mid level jumpers with the correct training.

The proper way to use jumper cables to boost a low/dead battery: (1) one end of positive jumper cable to "dead" battery; (2) opposite end of positive jumper cable to "good" battery; (3) one end of negative jumper cable to "good" battery; (4) opposite end of negative jumper cable to GROUND on "dead" vehicle. Remove jumper cables in reverse order.
Some good locations to purchase jumper dresses are Ebay, Nextag, Amazon, One Good Thread, Angelic Pretty, and Asos. Two more good place are JcPenny and Boohoo.
Yes, it seems very nice.
