Sinister is obcessed with the Summers blood line. I think that it doens't mater if it's Scott, Vulcan or Havok. He sees great potential is their genetics, but Scott was the first from the family to manifest is power so I think he was the first to be noticed. Havok has more control than Scott but Scott never used his power at his limits. It's been said that he's been limiting his powers unconsciously bcoz he doesn't want to hurt others around him. During the civil war Johnny Dee made him use his powers to overcharge Bishop and when Tony Stark measured Scott's power he said that it was larger than a large nuclear reactor. As for Vulcan, Sinister didn't know about his existence and as soon as he appeared he vanished.
