Ok I have to admit I am left handed in everything I do. So it came very naturally to me. I have spent 1000s of hours swinging other sports equipment left handed(cricket, tennis, squash) so I suppose the motion of a left handed swing was in me. The only reason I started playing right handed in the first place is that back in the day left hand golf clubs were more difficult to come across than hens teeth. Especially in South Africa in the 80s. But fortunately now I can get anything I want in a left handed version. So it happy days.
For me I think the most important thing regarding a golf swing is feel and practice. You need to feel as comfortable as possible with a certain grip, stance, swing pattern and then give it enough time and practice to get it going.
So find what feels the most comfortable and work with it for an extended period.
Good luck.
