You and I are the exact height/weight.
A person was under some influence of alcohol once after a party, and I made the mistake of trying to jokingly "shihonage" him.
He's about 250lbs, maybe 6"0 .
I'm 180lbs, 6"1 .
What resulted is him trying to grab me and slam me into things, and I kept instinctively avoiding and "blending", because going AGAINST his power was impossible.
Technique ? Maybe... if we weren't trapped in a small thin corridor.
I used his power ONLY, and we kept slamming each other into walls, not unlike that part in Terminator 2 where they, well, slam each other into walls.
I've also been able to show sankyo and shihonage to a security guard at work who severely outweighed me... and he was resisting like a person naturally would, which caused me to bounce between the opposing rotating movements involved, before settling in which direction I'm going.
