What will be your Secret weapon as a Batsmen or Bowler?

Im and all rounder. Im working on bowling the slower ball. It's going well in the nets. As for batting....I do this thing where I charge (off a spinner) 3 in a row...then on the 4th ball start to charge but move back to the crease, the bowler will bowl the ball shorter because he thinks you are charging and then you can crack the short ball for 4. Not game enough to try it in an actual game though.....lol
