Thanks for clearing up that very important point. I think we are back to the asking your instructor to do what you are paying for option. Instructors are very approachable (no pun intended) and usually enjoy answering questions and solving problems. Second guessing what you might be told and what might be demonstrated may not do you any favours.
For what it's worth, I find a powered approach and landing in a 2 ton light aeroplane a lot easier than in a less than 1/4 ton microlight. Sometimes momentum can be your friend and a lack of it means quickly nailing your attitude to the speed you want, at any power setting, is very, very important.
