Shots off the front wheel - rule?

Here's another problem I have with involving your bike in playing the ball.

offensive player has the ball and charging on goal, defensive player can hook the offensive players mallet to prevent a hit on goal. If the offensive player can hit the ball with his wheel to score then what's stopping the defensive player from using his wheel to stop the offensive player from getting a hit on goal? Considering that we're talking about front wheel hits, then this almost guarantees that the offensive player goes down due to purposeful bike-to-bike contact very similiar to a 'T-bone'.

The argument about less rules means to me that if you just disallow the maneuver then you don't have make a rule saying you can score with your wheel only after a 'hit' and then keep one rule about like to like contact and then make an exception to it effectively creating two seperate rules. So IMO three rules are needed to make this play fair.

Remember Jack from Sick Buckets and his concept of bike-to-bike?
If using your wheel more and polo becomes more radball oriented, in a worse case scenario, I predict that you'll see more plays, like, this. (yes, poor example but best images I have of gray-area bike to bike contact)
