My number one method is also partial hanging and I also have the same question. Im not sure which position is the best one but I think I will go with the one where your legs are straight and infront lf you. Tbh the other position where you bend your legs under yourself seems to be more comfortable but it is also very easy to just stand up in the position. I saw a thread where someone said they attempted and passed out and then woke up standing! I have asked here on this forum if this really is possible and if anyone else also experienced this but i never got an answer... So idk if that even is possible but if it is then having your legs straight will probably make it harder to just stand up right? But again, I don't even know if that is possible at all, it is just something a random member said they experienced. If I hang myself I will probably bend my legs in position 2 and when im down I would qickly put out my feet in position 3. But thats just what I think would be best plus I haven't even tested that at all yet so at the end of the day I can't answer which position is better. Im sorry you haven't gotten a good answer yet.
