Lynn and Lyle have agreeable points. Dumbing down technique so someone can "do it" circumvents the purpose of learning effective technique.
More importantly, it's the technique that leads to aikido as it represents the planet, universe, etc. My hope is students find effective and real technique (non-physical) outside the dojo, not just inside.
Being a good uke is equally as important as being a good nage. This is a criteria many instructors includes on tests. If uke gives nage dishonest energy for a technique, nage ends up doing henka waza, not the prescribed art.
If a partner is having a hard time with a technique, slowing it down sometimes helps, trying different perspectives, etc. But shouldn't it always be earnest, realistic, and sincere?
