Slasher, you're right, and sink rate is too.
The fact that alpha protection is lost when in manual thrust is another disgraceful piece of design by the Seattle 'experts', but is probably not a daft as the lack of automatic stowing of the speedbrake on advancing the thrust levers.
Both features should be available, and an inhibit below, say, 100ft RA covers the point about alpha protection on landing. Of course, the 737 doesn't have this.
