HD123AA

There is a PA-747 ABS plastic main blade
and
There is a ABS plastic main blade

PA-747 is Ultra-High Impact Strength

ABS wo any designation could be PA-707 or PA-757 or PA-717C which are all weaker ABS
so
It looks like to prevent blade eject on the 150x higher head speed you need a stronger PA-747 ABS plastic main blade

IMO go with the stronger HD123AB
or
CB black tip green PA-747
or
EB black tip orange PA-747
or
BB black tip white PA-747
