This has been an ongoing issue with me. I just started playing hockey a couple of months ago, and I can't figure out which stick I should be using for the LIFE of me. I'm heavily right side dominant. I write, bat, throw, and golf right handed. My dominant foot is my right as well. I naturally started playing hockey with a right handed shot, but quickly noticed the majority of my right handed buddies shoot lefty. I've asked them about it but they've all been playing for soo long that they can't really relate. I've also been taking a hockey course and my instructors are both right handed and shoot right. I've asked them about my dilemma and they just say "whichever way is more comfortable".
I totally get having your dominant hand at the top for puck control, but I don't understand how people shoot lefty when they're right hand dominant. My puck handling feels a bit stronger with a lefty stick, but my shot is basically NON EXISTENT. I workout heavy about 5/6 days a week, so my left hand isn't much weaker (although a bit) than my right. I feel 100X more comfortable and in control when I shoot right. So there seem to be obvious benefits to both.
Now I'm just babbling, but anybody feel free to chime in here. I've read numerous responses where coaches have insisted that their right handed players play lefty, and that in the long run it will pay off. I tried to play with a lefty stick one practice and it was embarrassing. Of course we were learning how to shoot that day...
