I'm not sure whether those are any good, actually - I've been told that if you're left-eye dominant, you should have a proper left-handed bow.

However, these days I shoot a longbow, and many of those are two-sided - I remember one shoot I was at where a left-handed friend's bow broke, so he borrowed one from another right-handed friend, and they shot on alternate details with the same bow! (My longbow is actually a 'right-handed' one - it only has an arrow plate on the left side of the grip.)
