S. Takeda was a small person who was able to control and "trash" jujutsuka and judoka much larger and heavier than he, and in fact stated that women and children could learn and execute these principles.
Of course, how many people are at the level that S. Takeda was?
For the rest of us, size is very much a factor. It may or may not be the deciding factor, but there are very few people for whom it doesn't figure into the equation at some point or another.
