Re: Why do we use so much grappling in Aikido?
Good discussion. I think that is why I like all three AIkido, Judo, and BJJ. Aikido does an in depth study in one range (mid range). One in which weapons work very well. Judo does a good job, I think, working close range, stand up, grappling, and BJJ, of course ne waza.
Of course, there are things that can be added and assumed in each phase with cross over, but I think, they each have merit in and of themselves.
I also believe in studying them separate and distinct as I get a great deal out of the experts that have refined skills in each of these systems that might be lost if they were combined.
Anyway...just some thoughts, good discussion.
