Re: Baseline skillset
I agree (for the most part) with Erick's assesment of the forward movement, focus and weight that is a basic for Yoshinkan. Mixing that approach with some of the specifics that Mike gives is somewhat problematic...but to suggest that a difference in which foot you weight negates the connection between the skillsets is kind of silly, in my opinion. There are styles of aikido that are very powerfull that don't focus the weight in the same manner as in the Yoshinkan. Since I cannot conclude that "our" way is necessarily better than "theirs"...I must then conclude that Erick doesn't quite understand the topic.
Shioda is rumored to have had some instruction outside of Ueshiba in Daito ryu...I cannot say how much, and this is often debated. But it should be noted that his licenses from Ueshiba were in Daito ryu, and that Daito ryu and the Kobukan dojo, are said to have invested heavily in this kind of internal skill set. Hard physical training does not contradict the internal training.
