The mornigs are good I will agree, but late evening is the best if you want to see the hunting cats come out. If you go right before closing, I mean like minutes before they stop letting people into the line, and wait for the last truck (not that long if you went in with a few minutes till closing) you will get to see the lions playfighting with each other. I once got a Lion King picture with both of the lions standing side by side on the rocks looking out. It was one of the most beautiful sights I have ever seen. Also you get a chance to see the leopard walking around. I once saw it running full ot in the trees. So if you do the morning safari go back to your hotel and chill until the park has about and hour till closing then go in and ride CTX a few times then head to the back and do the safaris you will not be disappointed.
