Squats are all you really need for quads and hams anyway. So ditch the extra day and spend more time squatting. Throw in some stiff leg deadlifts and calf raises, and your legs will be set.
I'm sorry, but I have to disagree with that. My hams were not getting hit like they should have been until I added glute-ham raises. Although squats hit everything, I still think that additional ham work should be done.
