Better software for training in chess openings?

I own Fritz 13, but the opening training seems linear, IE both sides will be playing the same opening. For example I would like to train Vulture, so I play white, and black is also playing vulture, which does not seem realistic. Is there some better way/software to train the openings?

give a try to Lucas Chess!
it's good and free ;-)

Try chessable.com if repetitive learning works for you. Some of the opening repertoires (like the free Caro Kann one) allow you to practice both sides.
