First of all, Nicky, the rule does not allow for that. As Simon pointed out you must play it with the playing area of your stick. The puck may rest against your finger, not be propelled by it. What has happened is that people are doing it and the refs are not calling it. Part of that is that the ref shouldn't make calls that are perceived infractions. The refs should make calls they see. This one, however, can be (I don't know about should be or actually is) perceived acurately. As a right-handed player is coming up the pool he comes up against an opponenet and quickly moves his whole hand/stick/puck left without dipping his stick back to allow the puck to get moved by his stick rather than his glove. I know in this situation it is fast and difficult and real easy to say "so what". But now put that same move on the right wall and have the guy move the puck up the wall using his stick strictly as a tool to keep the puck against the wall and the glove as the propulsion to move the puck along the wall. A bit different? Not at all. It just is a bit more obvious along the wall. Changing this rule opens up that and I don't think that encouraging a wall game with this rule is any way to open up the game.
