Thumpango, why on Earth does your flying school require you to fly so fast on the approach? Tell them to re-examine the Pilot Operating Handbook for the Warrior.
If you fly too fast on the approach, you will have difficulty in landing because the aeroplane will be out of trim. You have to manage that out of trim force, as well as finessing the flare - and that is MUCH more difficult if the approach speed was excessive.
Your comments about pre-loading the control column thus 'allowing the column to move in the direction you should be moving it in the flare' are indicative of developing a personal technique to cope with flying the ac far too fast on the approach. Perhaps you should go elsewhere to a school which teaches you to fly aeroplanes as the designer intended?
No wonder you're having difficulty in learning to land the aeroplane! Not your fault - it's definitely theirs!!
