Skeeter, with an underpowered machine, I think it's even more important to keep the wind on the correct side. There is some weathervaning tendency with any helicopter, and counteracting that requires power from the tail rotor, which subtracts power from the main rotor. With the wind on your left side, you need more right pedal to keep the nose straight, thus you're using more power, and come closer to reaching torque or engine limits, or even having an exceedance of some sort. It's not always possible to keep the wind on the correct side, but given a choice, I always do it.
