R44
ReverseFlight - I remember my instructor (who weighed all of 150lbs) putting ballast under the left hand seat in my R22 in prep for my first solo. Thinking back, the ballast can't have weighed more than 20lbs, so the difference wouldn't have been that noticeable, even with such a light instructor. Maybe the placebo effect gave me more confidence (not necessarily a good thing!)? Providing the stude can lift nice and slowly into the hover, surely the difference in a/c attitude due to weight & balance is no worse than compensating for the effects of a stiff breeze?!
