I have a good friend that switched. He did great with it.

I bought a used left hand bow years ago and found I could shoot about the same with practice. I am right handed, left eye dominant. I did however ended up selling that bow. Then a couple years later, I was told by an instructor that the best way for me to get better was to shoot lefty for eye dominance. I bought another left bow and found it completely awkward. I took the bow back and am glad I did. Some can do it, but if you're not physically built for it like me, it could be a long, hard transition.

It has been about 2.5 yrs for me.  I started tinkering with it, borrowed LH bow from a buddy.  I would go back and forth.  Then on a hunt in Idaho in September 2014, I had the TP so bad that I shot a longbow with a leather plate electrical taped to the right side of the bow so I could shoot it LH.  That ime in the mountains was the turning point for me when I "knew" my future shooting a stickbow was LH.  Today, I have no issues shooting LH.  Nocking the arrow, fluid, snap shot; something that TP took away from me right handed.  I came to a place of "acceptance" that I needed to change.  I tried everything RH, but I could not regain a fluid snap shot shooting style that I prefer for hunting.  The cool thing is left handed mind does not know anything else.  If I was to use a gap or reference aiming system I believe the change would be more difficult due to my right eye being dominant.
