Didn't see this post. I "toyed with" running a PPL on a 4 day per week basis which will get everything worked 3 times over near a 2 week period.
As you get older I think the greater frequency requiring the use of more compound movements keeps your hormone levels higher, remembering our hormones take a dive post 30. The extra hormone level may not result in greater muscle development but it will certainly will give you a greater sense of well being and health. The added frequency should give you more muscle development once your body has adapted to the frequency.
Have you thought of running a 4 day PHAT?
Yeah I ran PHAT over a 5 day split for a few months towards the end of last year. Didn't mind it, saw some strength gains but the way I was structured it was a lot of volume and I found the workouts just went for too long. I can't do 2 sets of anything so 3 was the minimum. I also added in forearms and another traps exercise I think. This was my basic template:
