In karate competitions you can hold a grip with one hand - atleast for a short time. Two hand grip will be a warning. I am not looking for takedowns from opponents kicks. More like continueing from situations when both are too close to score with kicks or strikes. (Hooks do not give points for some reason.) Maybe some MMA guy might have ideas?
One hand gripping the gi? De Ashi Harai works well i find, or a 1 hand Tai Otoshi. No hands sweep by stepping deep to their outside behind and sweeping over the legs, Sukui Nage style is great too
