I was told, that Uchi-Mata is a good throw for bigger (more height) people. Being rather small myself, I can't test it though
Any leg reaping attack would be good hip and arm throws probably less useful as you have to drop your centre that much lower. O Soto gari, o uchi gari throws where you can take advantage of your length to push pull or load them onto one leg advancing footsweeps etc as you can hit them at a distance that they can't on you lol Hari and uki goshi over full o goshi as it's easier to get half hip in than the full one on a smaller opponent
I don't judo regularly at the moment, but back when I was, playing the range grip fight game, then either hopping osoto etc attacks, or tomonage /sumo gaeshi style throws worked best for me. When your taller, it's easier to get the feet in the right position but you tend to have less force, so chaining leg sweeps etc helped a lot too. But if I'm working with much better people, if I over play grip fighting then I just get launched hard, so I tried to limit always going for dominant grips, and just tried to not have inferior grips, if that makes sense?
Tomoe-Nage might be an interesting to use if you're lanky. Keeping your arms straight and then shoving a foot to the hip..... May have to ask my group's resident 6ft 5-er to do it on me.
Thanks I have indeed tried it and did it a few times to smaller uke's it's a risky throw high ranking though but I am 6 ft 4 and seems to be a worthy throw for me to try hopefully perfect more myself!
I resorted to leg reaps, sweeps, body drop the most. Definitely easier to get your feet in position with longer legs. Hip throws I found harder to set up as you have to drop your hip further down to get the right level, but hand over the top round the back for those throws when you do them on shorter people.
More good advice keep it coming if possible, Now I do like the hand over the top grip seems to work well for me but have not came close to mastering any throws from that exact position yet a it is a work in progress.
