Would be hard to beat Hooks Shear Force 38K.
We've been using several Shear Force sons & grandsons over SimAngus and ANxSH cows. Like what I've been getting, and docilities are good.
Last year's calf crop was mostly by PRS Blazin' Hot W192... heifers are nice, and he put white faces back in the mix. Too soon to tell how they're gonna be as cows.
Previous 2 year's SM calves were mainly by Long's Shear Pleasure(3/4SM-1/4AN). Very docile,and they're looking good as bred heifers.
Oldest producing cows,since we came back to the Simmental side, are a couple each by Dikeman's Sure Bet and Triple C Singletary.
Sure Bet may be the best balanced bull out there - not the highest WW epd available, but better than a lot of the ones that seem to show up behind show winners; good calving ease, great docility, moderate milk, great marbling/ribeye/tenderness. I'd go back to him again in a minute if the farm manager wasn't all about high WW and white faces, right now.
SimAngus... I'd probably go for SDS Graduate 006X - a 5/8SM Shear Force son out of an ALC Big Eye daughter. More calving ease than you need for cows, but should leave some really nice, docile daughters that'll produce calves with good carcass traits. Was looking to buy a Graduate son in a recent bull sale, but he failed his BSE.
