What are some good barrel racing bloodlines?

i am partial to pacific bailey, jet deck, go man go, easy jet, leo, war leo, dash for cash, three bars, pretty much any racebred quarter horse or high percentage tb (over 40%) crossed on cow or working cow lines like king, leo again, doc bar, poco bueno- any working line that has produced race offspring. you dont need much working blood a bit seems to take the edge off the the tb. i have heard good things about bully bullion and sunfrost horses.
