Well, hopefully you understand color genetics...I'm gonna assume you may not, so forgive me if this post is below your level of understanding. The two registered Limousin heifers don't carry a spot gene, so in order to get "color" out of them (assuming we're talking about white markings), you'll need to use a bull with dominant color markings...a white face or a true white gene like what causes roans in Shorthorn. I'd say you're on the right track with the two bulls you mentioned, but I'm not sure a bull like Capiche will transmit that roan or white gene consistently...I don't know, but I would be skeptical. I would think there's a good chance at getting a baldy out of Carpe Diem, but that's based on the fact that he looks like a Hereford, and I know he's not purebred Hereford, so I don't know if he throws some solid calves or not. I'm just saying all this because it's disappointing to think you're gonna get a calf that looks like the sire when sometimes that can be genetically improbable or even impossible... So understand what you have, what you want, and what it takes to make that using those females.
As for the other two, an Angus bull will offer you solid black color genetically, so you would be relying on the females to provide any color there, and again, it would have to be a dominant gene in order to show up--white face, roan, or dilution (smoke). You didn't mention what color those two heifers are, so I don't know what you're working with there.
In terms of type, I personally don't see Final Answer on the list of show calf sires, and I'm not familiar with the other Angus bull you mentioned. He may be a popular bull that just didn't register or isn't on my radar... Final Answer offers great calving ease as well as a lot of production advantages, but I don't see his place being to make show calves. I would think something like that would only work where you might have a real clubby female that looks more like a steer than a heifer. I think in general there might be some better options if you want to use an Angus bull.
