That's an interesting perspective. I don't have much experience with Shinden Fudo ryu either (it is a challenging school for many reasons) but I think part of the reasoning behind that statement is that the dakentaijutsu uses every ounce of your body as leverage behind the techniques, which certainly isn't exclusively useful to smaller people but are valid mechanics nonetheless. A huge overarm smash might be what a small person might need to do to match the jab of a large fighter....?
Example waza (listed as ura version of Gekken): taking an outside wrist-lock within a standing onikudaki shoulder lock, throwing the opponent by leveraging these locks while performing osoto gari, and falling with the opponent on top of his locked wrist with your center of mass. Essentially uses multiple points of leverage to bring down the opponent from a single, central movement, and literally hits with the whole body on a single weak point. In fact, many of the kata call for putting on locks by rolling, which really leverages everything you have into the technique.
I'm not familiar with any technique in this ryu that calls for picking up the opponent and body-slaming him. Could you find and example of this? The closest thing I can think of is the "dragon drop" concept, where in mid-throw you stall the opponent on your body and than pull out from under him, allowing him to free-fall from several feet up (and in an awkard alignment). Even in this case you are usually "catching" him in mid-fall on your hips long enough to stop rotational movement and then moving out again, not directly lifting (though you might "drop" him by standing straight-up, giving a slight lift).  |
