After 3 or four years of trying to get it right and trying new things my current approach seems to be working best for me. Once visual I just stay glued to the glidesplope (if I have one) with my eyes out about 60% of the time right down to 100ft, then I transition to 90% outside with glances in to make sure the airspeed isn't decaying and by being on slope at 100ft I find I'd be struggling to land long, at 50ft rad alt call I move my eyes from the aim point to the end of the strip and just fly it. I've given up on trying to put it on extra smooth and like the other poster said just put it in the right place at the right speed. Funny thing about that is that now I am often doing 'nice' touchdowns as well as getting it in the right place. That did take a few months to come right though. Not sure if that helps but it's my experience.
