I want an uke that does not move in a pre-programmed fashion at any time;
Sorry, just to clear up a contradiction in what I said.. I shifted from talking about kata to randori where the difference is intent.
Obviously, during kata, uke's movements are pre-programmed to the extent that allows me to learn the technique being studied.
What I intended here was to indicate an uke who just follows along, regardless of tori's inefficacy.
