What I don't like about rebound control is the automatic puck pick ups it tries to do. Sometimes you get the "hungry hungry hippo" animation and since the puckis right there at the goal mouth its so easy to just tap it in.
With the rebound control low and my shot recovery at 95 my player instantly recovers from any and all save animations to make multiple saves 3-4 and even 5 in succession when needed.
Plus with the rebound bouncing out a bit more it gives more of a buffer time for me to reposition and make move saves which coincidentally raises my save percentage.
