If you can get semen on him. If not, you need to look at DAJS Shockwave, a good Hot Rod son, he also is a little hard to get semen on right now because demand has been high. Is she a heifer? If so I would go with Connealy Final Product or SAV Brilliance.
Hot Rod needs to be used on a clean fronted female. I would not use hot rod on heifers. If she has some guts then Final Product would work, otherwise Brilliance would be a good choice.
Did not know that she had already calved. Hot Rod can be used on 2nd calf heifers. Shockwave is available, http://www.cattlevisions.com/Angus/DAJS_Shockwave.php, but you would have to contact Satree's for certificates. I haven't found any on the bull.
You might want to also consider Silveiras Style or Gambles Convoy.
