Re: Kata dori - tips to remember
Sensei would sometimes teach the kata dori techniques with uke just using an open hand - resting the hand on nage's shoulder instead of a grab. This would emphasize the "awase" blending feeling you should have so you don't separate from uke (if you step back instead of to the side, for instance). This kind of practice helps you get the blend for the jutai form. As you mentioned, Sensei taught the ryutai form (which resembles ai hanmi katate dori) as a foot change / inside tai sabaki to a 45 degree angle in front of uke, grabbing on top of uke's hand, pulling slightly forward and down to make a small kuzushi before performing the upward, circular ikkyo movement.
