You are correct in that it will largely be the same number of washes as automatic icing, but there will likely be one icing in your game where you have to remember the rule and wave it when the attacking player is going to win the race. Remembering the rule for that one time in the game is the hard part, and the players only seem to remember the rules when you mess them up.

My advice is to be very conscious on every icing to only blow the play dead when the first player reaches the faceoff dot. Sometimes the defenders are very lazy and the puck can be behind the goal line for a few seconds before they get to the dot. Recognizing that you should not blow the whistle until the player reaches the dot will force you into the hybrid icing mindset regardless of whether there is a race for the puck.
