Preminition is a Genex bull that won the Iowa Beef Expo a few years back and Genex bought him. They still sell semen on him. I have two Gelbvieh cross daughters in production from him and they have done nicely.
Floto II is likely a Fullblood, I have heard of him, but he was before my time.
I think Ellison was a stout, black Gelbvieh bull from about 10 years ago when the black hided thing really took off in the breed. He may have some Eagle Pass breeding, but I'm not sure.
Any bulls with the KCF prefix will be from Knoll Crest Farms. Most of their genetics show strong growth epd's, but sometimes aren't as attractive patterned as you would like to see.
You mentioned Freedom & Advantage. I'm not sure if you were wanting info on them as well, but in case you don't know, these have been two of the most popular bulls in the breed the past few years. Freedom was far and away the most heavily used bull in the breed for about 4 years. His progeny grow well, come early, and are very attractive. Freedom progeny have dominated the show ring and breed sales. His milk epd's really took a dive over the past couple of sire summaries. I never useed M/L advantage although he sports a really complete set of epd's and I believe he is homozygous black and homozygous polled. He is an extremely long patterned bull.
Hope this helps.
