Personally and individually, I'm a large advocate of super/drop sets. I also respond to higher volume (sets x reps x time under tension). And because volume is a component to hypertrophy, I feel FB routines do not apply this.
If you're looking to change your routine, consider the following:
1) using different exercises, different order of execution, etc.
2) sets and reps to stimulate different forms of hypertophy (satellite/contractile proteins or myofibrillment, specially).
3) changing rest periods accompanying #2.
4) frequency, volume, order of muscle groups.
hope this helps. Changing a routine isn't very hard, it's finding one that works.
