I have never really taken the time to learn about different aspects of blades. Whats the difference between a heel curve and mid curve? Does one make it easier to control the puck or easier for a certain type of shot? I know the depth of the curve effects shots and puck control, but can anyone enlighten me on which types are better for certain shots? Generally speaking of course. If you can't shoot for crap, you can't shoot! The face of the blade. Whats the difference between an open and closed face? More control of the puck with a closed or open face? Better shots with which?
