I'm quite glad I never got into this "lucky left" mantra thing. I mean say you're slowing on a photo flight in the R44 and you find yourself at full throttle, but not really paying attention (as in a number of R44 accidents I've read about) you push in "lucky left" and things are gonna get "rotten" pretty quick!
As for wind. If I had stuck left pedal in the R44, I think I'd rather have the wind on my right.
