shortii,
I'm fairly new to the Shorthorn deal - have only been breeding to SH sires for about 3 years - and we're strictly commercial, breeding SHxAN to make COWS - not into the show/club deal, so take this for what it's worth...
Waukaru Goldmine 2109 is the real deal on calving ease - have seen enough of his calves here that I'd even use him on all but the smallest Angus heifers in my herd, and not have the slightest concern about 'em calving out to him.
Have a few RS 034 and Captain Obvious calves out of second-timers, and their CE/BW epds are good enough - and calves came easily enough - that I'd not worry much about using 'em on well-grown heifers of most any breed.
Bred some second-calf cows to Waukaru Gold Card 5042 this fall - don't anticipate any problems, but did not breed him to any virgin heifers - though he may be 'heifer safe'.
Check out the SH offerings at CattleVisions - you can sort 'em by BW epd and compare CE/BW as well as 'own birth weights', etc...
Code Red looks nice, and his CE/BW epds are good enough that I wouldn't back away from using him on 2-yr old second-calvers, but after hanging around here(SP) for a while, I'm still real cautious about the SH birthweight deal and virgin heifers.
