I don't have Timesaver since I have the rest of the BB series, which has tons of premixes already. And if I prefer to not use a premix, I can always mix and match segments on my own.
I love CTX. It was the last series I got (that was before Cathe made the BB series) because I mistakenly thought it was like most of her endurance workouts. I was very surprised at its versatility. I've never used CTX as is. I got it mainly for the UB split and LL. And on days when I don't want to do an entire upper or lower body split, I'd do my own hybrids of segments. It's not as finely chaptered as Cathe's newer workouts, but I've done just fine skipping or fast-forwarding in places.
