Thank you all for your comments, these have been very helpful and exactly what I was after.
I fly a PA28 and I find it just wants to keep on going, it seems quite happy to float along the runway for what seems an eternity!
I guess I might be trying to touchdown too soon.
My next lesson is this Monday and what I have picked up from these postings is to continue the holdoff as long as possible and pitch up when I detect the 'second' sink.
Bleeding the speed off takes much longer than I originally thought even with 75knts and power off over the numbers.
And if a slight balloon occurs, would you add a little power to rectify the situation and flare again? or abort and go around. Depends on runway length most likely.
As for Examiners, I am surprised that an examining CFI can test students from his/her own school, although from the students point of view this must be good I would have thought!
