While they both appear to be very nice bulls, I'd opt for the older bull as he appears to have more length. That being said, I'd also like a peek at the EPDs...even though numbers can be manipulated to some degree it would be interesting to see what they have to say about each animal.
Vacation and Chateau are both Genex bulls. I have sons of chateau and one of vacations. A neighbor who used to be the Genex rep used vacation a lot. I prefer the muscleing of chateaus calves. After seeing the neighbors calves, I still prefer him over vacation. But I do have a couple of cows bred to vacation this year.
I spoke with the guy today that used a lot of vacation and chateau. He said he is really kind of disappointed in the vacation calves (muscleing) in comparison to the chateau calves with one exception. He feels that the vacation calves out of his chataeu daughters are some of the best calves he has this year.
