Hard core steer producers more often than not are looking to buy individuals, not groups of cows.
I would guess most of your potential buyers - both show cattle oriented (relatively few) and good commercial outfits (much larger market) - are going to be more interested in maternal genetics. To capture the wides potential market - breed them Simi - something with a name to catch the show cattle folks eye. Your potential commercial buyers won't care as long as they are Simi bulls. Good options for Simi bulls are almost endless, but I would consider any of the good Meyer sons (i.e. Macho), Steel Force or Chopper, or Star Power (probably a real good choice from a popularity standpoint).
If you have one or two standout cows, you could go show steer sire on those.
