FB Fit vs FB Blend (choices choices)


As I've done the FB Low impact program multiple times I'm looking for a new one.

I'm doubting between FB Fit and FB Blend. FB Blend is 4 weeks, I'd like a 8 week program, FB Fit is 8 weeks, but I'm unsure about the length of workouts. How many are more then 60 minutes?

Experiences from anyone?
