One of the people I trained with at Multnomah Aikikai was second dan I believe, and he just didn't like training with weapons. For one reason or another, he decided that he would focus all his energy to "physical" practice.
He is, fantastic.
His knowledge of aikido blow me away, and I find it very interesting that his insight is unique is certain ways. Who knows, if this a function of little weapons training, but I find it very interesting.
