I've still stuck with this routine. I found myself training already-trained body parts and just doing small pump exercises to get blood through everything while it was still sore. Never went beyond warm-up reps and just did a couple compound movements.
My workouts slowly evolved into full body workouts, which is something I would never picture an advanced lifter doing. But I'm still responding well. Each day I still have a "focus" muscle where I reserve most of my intensity. Instead of just pumping everything else up, I do fast sets (about 4-5) and a few exercises for each body part. Doing chest/back/shoulders/arms/legs, more or less. But sometimes I'll retrain (with lots of intensity) another body part which I had worked out just a couple of days before.
I'm finding that I'm still growing and still getting really conditioned. I'm able to train my body parts way more frequently and still get them sore. There is still a couple days of soreness, but I can lift through it without my strength being impeded. I had to cut my weights back a little bit, but the intensity is out of this world. Volume is very high and everything is very fast. There's no such thing as muscle wasting or anything from high volume - just glycogen depletion. I eat like a porker so I don't ever get too flat. I burn about 500 calories using the stepper each workout (mostly to pump my calves, get warmed up and to do actual CARDIO). Sometimes I burn a thousand calories. I used to think I would get flat, but I still get super pumped. I'm not running any supplements or anything. Just a little bit of test enth which I haven't run in years.
I don't think I'll change things up for a while because if I miss a few days at the gym, I can always bank on having just done a full body workout more or less. And if I know I only have one workout or two to make things count, I'll have a damn good workout and that'll be that. Little drunk right now. But I like no one's approach. I was able to meld it with what I was already sort of doing and it's going good for me.
