Deload Cycle

I've just taken this cycle lightly. No ultra heavy lifts and more easy cardio. I'd like to take a few minutes to reflect on my cycle method. I basically do hamstrings one day, quads the next, and upper body the 3rd day, followed by a day of rest. That's one cycle.

Pros:
1) I like resting every 3 days. It encourages me to work extra hard during work days.
2) I like leaving cardio as a supplement, so I can do what I feel like that day

Cons:
1) I shouldn't have 2 leg days in a row
2) I don't have a structured lifting program. Instead, I design that day's workout the night before.

Should I find some lifting program now and follow it more strictly? I sometimes use the Figure Athlete site to get ideas. Will report back with some ideas.
