The light day would be eliminated. My disagreement with the faction that advocates little use of supportive equipment until the end of the cycle, is that a lifter needs time to get used to the feel of supportive equipment. Also, time is needed to test equipment to see if it is doing the job or needs replacing. This is especially important to a newer lifter who has had little experience using supportive squat gear. The gear changes the feel of the squat immensely.
More experienced lifters know what to expect.
By gradually introducing the equipment, you will not be addicted to its use and you will still gain in strength over the cycle. When a lifter steps out on the platform he should be using all the equipment that rules and his budget will allow. He must also be familiar with its effects during a max squat. By incorporating the system I have just described, you will get the best of both worlds. You can adjust this routine to fit your own squat routine.
