It depends on a lot of factors. I haven't used the FD on my aircraft (Cat 1 only) for about four years now. This stemmed from the need to keep in raw data practice for my CAA IRT initial issue, but I have got into the practice of not using it.
I would like to point out that it is a particularly poor FD, and I found I could do a better job as it is reactive, whereas I can anticipate changes in drift down the approach. My company SOPs don't require it to be used, and a lot of my colleagues don't.
