I'm with the King - the SimAngus would be my choice.
We're currently doing a 3-way cross: Angus bulls on Sim/Shorthorn cows or black Sim bulls on Angus/Shorthorn cows.
TXbred - we ran a halfblood Simbrah bull on black baldy cows in south AL back in the late 80s - best calves we EVER raised, and the heifers made darn good cows. Good enough that I've kept some Simmental influence going in my herd for the past 25 years now, but up here in the 'frigid northland' of KY, I don't need any 'ear' or the price dock it would bring me.
wtrapp doesn't really need any Brahman influence in middle TN - I practiced there in the heyday of the Beefmasters & Gerts - and they're good cattle in the right place, but I wouldn't want much Brahman influence down there.
