You asked about leggs. There were 3 brothers Leggs, owned by billy Joe Fisher, of McCloud. Leggs 2 owned by the Holloway family in Chattanooga, OK. Len Ru Ta Leader owned by the Kaba Ranch , in colorado.
EAch bull produced a grand a a major show in the 80's and 90's. I personally owned daughters from each bull and owned kaba Keystone. I would love to have some of those females today. The steer side was smaller framed and easy keeping. Those bred for larger framed cattle got what they wanted too. Larger cattle with a sweet look.
Bulls in todays genetic horizons list that include KABA breeding are Ace of Diamonds, Chiller, Surf, Snappy, American Outlaw, American patriot, Handy Dandy, Perfect timeing, absolutley, tobascoe, Rocky, Casper, Vortec, Double leader, keystone, Get serious, Polar Express and Fringe, and probably a few more.
Len ru ta leader had several sons that were producers, My bull Keystone was known for his powerful steers. We had to breed him to stretchy long fronted cows to get steers big enough to win. First calf crop produced champions at the Iowa state Fair, Missouri State Fair, Res. Chm, Wisconson st Fair, Champion and res Grand at the Texas state fair, Champion Tulsa State Fair, Champion Ft Worth state fair. That year at Ft Worth, keystone calves won half of the shorthorn classes and had 7 steers in the top 5 of their classes.
There wer 2-3 bulls that produced great females in a larger frame. Those prodigy finally produced today's vortec.
You can't go wrong with the kaba lines. I hve not kept up with Joe's herd, so I don't know what is going on today with those genetics. At one time they had the genetics that were in demand.
