Thats a great video...Thanks for posting it. I too am gonna practice it!
Cross-dominance is a bit odd, but I've got enough control over my left hand that it really isn't much of an issue for me to shoot left-handed. I've used my left hand most of the time when I've been to a range, so it seems pretty normal now.
The only thing that bugs me a bit is that since my right hand is stronger than my left, it's easier to shoot one-handed with the right hand vs. the left hand. Hopefully I can build up more strength with my left hand so that it won't be an issue. When I occaisonally practice one-handed and use the right hand, I tilt my head to the side so I'm still using my left eye. It works well enough, I suppose.
I'll try to work more on shooting with both eyes open, but I've never been able to close just my left eye, for some reason. I can only wink my right eye.
Thanks for the tips!
