If DA is not an issue, and I have a good power margin, I prefer to come in crabbed to the right with a turn into wind on very short final.
If DA is an issue, or I have a small power margin, then I prefer to come in with the wind off the left.
I used to have to go in and out of a hospital pad that required (with prevailing winds) that we flew the entire approach downwind, even when winds were 20 kts....just had to take it really slow as we approached loss of ETL on approach, and then take it even slower from there.
But hey- every helicopter has it's quirks, and every pilot has his method of dealing with them.... good luck. I don't think there are any hard and fast rules for any approach.
