Go to your profile and click on it, top right, and add a location so we don't have to continually ask you. Good advice is often location specific.
It can be a bloodbath. 
Got to breed them to Char. Or Angus
Correct.
LH heifers, for the most part, won't have that massive spread like the one in Brute's video, until they get some age on them. All LHs don't have those 8 and 10 foot spreads like that, either, even when they are older. Most you see like that were selectively bred for horn size and width. For show cattle...for expensive pasture ornaments.. You mentioned you wanted to raise registered LHs, so is that the market you are going after? How many LH heifers and how many Brahma heifers are you talking about putting in that 100 acre pasture?
Because we have been on this board a long time and some one who doesn't know if they can run certain breeds together (which is ok) likely does not know stocking rates in their area. We have seen the heartbreak 1,000 times when people find out their 100ac property is in a 20ac/head area. Especially when all those LH and Braford heifers turn in to BIG cows with calves on their side and you are wanting to hold and develope animals for a breeding program. It gets tight.. quick.
We will raise LH for breeding because we quite love them and both have had experience with them. Considering breeding F1 Braford also, which has interested me recently. Which is why I'm asking since I know Brahman can be particular. We are in East Texas, in great conditions, and already working on improving field conditions more. This will be a well-maintained pasture(s), including legumes and grains that we are setting up for year-round rotational grazing. Should be easily able to do 3acre/head. But will likely never have more than 20, and starting with a very small herd of about 5-6 for year 1 this Spring, which will be all Longhorn.
Right, I wasn't trying to get into stocking rates or numbers, because then we get into location, field conditions, and maintenance levels. But I did include more info below. We are not going in blind by any means. We are working with our local NCRS/USDA office, and several ranchers in our area. We've worked on their ranches with them, had people out to our land to help make recommendations, etc. But no one I know or we have worked with has run those 2 breeds together. In fact, the LH people we know seem to have very negative thoughts on Brahmans and Vice Versa. Which is funny, and why I posted the question here.
But such beautiful lawn ornaments they are! Yes, to some degree, the breeding market, but I do think there is a rise in LH beef too because of it's lean nature for those that don't "make the cut". We will be a very small operation.
It's not breed, it's horned cattle vs non-horned cattle.
... and Brahman cattle are notorious for segregating themselves from other breeds. Not always... but they definitely do it.
LH, in their own pasture where they belong.
I appreciate this.
