I have not mastered it yet but i am good at it and it is really fun.

If you approach it correctly, it can be VERY rewarding. If you don't have an open mind, determination,and/or approach it incorrectly, it can be VERY confusing.

I try to convince all Dealers at my seminars to learn to shoot both ways so that they can properly tune ALL bows.

I have no problem shooting left handed minus perhaps poundage compared to my handed style shooting. I've set many left handed bows up and shot them in before handing them to the rightful owner to finalize. You never know when it really might become necessary and it's fun to tweak and mess around that way.
