Wise words - phase advance is not a great idea and I have seen it go badly wrong more than once. People were too keen to use it.
If I don't like the speed it gives me, I either manually select a speed until I'm happy, or use manual thrust. Many of the approaches I do are speed controlled up to a certain DME from touchdown anyway - so the choice is made for me.
And if in a V2500 powered A321, man thrust is my preference anyway as IMHO, the software is often not proactive enough in gusty or turbulent conditions.
