Basically if the coupler can move side to side it will make the curve.  I do have passenger cars with the H couplers that do not even like 36 in curves but there is no movement in the coupler boxes.  All the tight lock F and H couplers hold just like their real counter parts.

I have grades up to 3% and once the trains are on the grade there is no problem.  I had to make minor adjustments in places where the grade meets level track.

I will add also that I have Code 100, 83, 70 and 55 rail and run a lot of 0.88 wheel sets.  Even as I built my layout I checked my work.  Once I had trains running I still found and still finding areas for improvement.
