Dad used to have a herd of registered Simmental cattle, before he got bit by the aircraft re-building bug and sold his herd. I guess you could call them "regular".
Currnetly, I've got both 'regular' and Fleckveih type bulls.
The Fleckveih bulls that I've seen around this area and in the Simmental magazine tend to be real meat wagons. Not a lot of leg, but very double muscled and extremely thick. The one I've got here is dark red and goggled with very little white on his body and legs, and has real old country lines, Neff right on the papers. He tends to throw calves with moderate birth-weight, thick backed, and 'short' marked like he is. They're a little shorter in the neck than the 'regular' styled bulls' calves are.
One thing to note that I'm very pleased about is that due to his genetics, when crossed to black baldies I haven't gotten any 'smoky' calves by him.
The calves from that cross are all black baldies. This is one reason that the simmental breed has shifted away from the 'blondes', as they are a genetic colour diluter and can sire those off colour babies(that the buyers just love to hate).
Anyway, they do seem to gain like there's no tomorrow.
The only thing I can fault the Fleck bull about is that he is so massive (2300 lbs on a 6.5 Frame) that he is a pretty slow mover and gets a bit sore on his front feet. He made a fair bunch of calves when we turned him out on the home place, but now that we're into the time frame where we get calves sired by the bulls when they're kicked out into the big community pasture, I've seen a marked decrease of his offspring (and his calves are distinct enough from the other bulls that they're very easy to differentiate). Even driving the cattle to the pasture (and we don't break any land speed records) was almost more than that bull could handle...he was almost a 1/8 of a mile behind the rest of the drag...tongue lolling, panting and puffing along, a real pain as he kept hitting the bush every chance he got (and it was a cool day when we moved them). Made me wonder how many days it took him to recover from a five mile stroll up the road and get back to work making calves.
So in the long run, it's up to the individual to decide what's going to work well for their operation. If you have less acerage for the bull to cover, then it wouldn't be a problem. But if you're like us, with a lot of ground for the bulls to travel to service the cows, the trimmer 'regular' simmie might pan out in the long run (as I noticed those boys covering cows the next day, same as the Char bulls).
I'd love to hear thoughts from others with either 'type' and their experiences.
