Drawish is the new decisive

After playing chess for about a year now, I have stumbled upon a great inconsistency in my play.  I used to be very agressive and daring.  But when I combine two of my three USCF tournaments during that era, I get 8 draws, 5 wins, and no losses.  I played very agressive openings during that period.  e4, the Sicilian, Poisoned Pawn French, and the Burris Gambit.  Lately, I have been turning toward positional openings such as the Caro-Kann, QGD, Rubinstein French, and d4.  For some reason, I have yet to draw when I play those openings in tournaments.  I have a decisive result every time.  This is a major inconsistency.  Why do you think this is?
