In WIAA sanctioned hockey you get a higher practice to game ratio. This should equate to better skills development. In the majority of cases the coaching is much better too.
In WIAA hockey players are held to higher standards of conduct, both on and off the ice. Also in the classroom with academics. WAHA does run some very good off season programs, but am guessing you are referring to just WAHA high school rec hockey.
One downside to WIAA hockey are the players themselves are some of the ugliest hockey players you will ever see. This is one reason the women don't flock to them like they do in MI & MN.
I'm surprised coaches don't throw pucks at their faces because these guys are so ugly.
I think that was the most random thing you've ever posted, even moreso than all of the Sweden stuff,  I don't know why, but your quote above made me laugh, I guess because it was just so out of the blue, whatever the hell it was.
