In the UK PPL of old exercise 25 Limited power we were taught Running T/O, Cushion Creep, Towering T/O and vertical climb. It seems that the UK consider that Towering and max Perfomance T/Os are different techniques and each have their uses.
I remember being taught that a towering T/O starts with a low hover or even a small ground cushion bounce followed by a vertical climb. Decision point was when the a/c stopped accelerating upwards. If you were clear of obstructions, you continued by starting a gentle transition that took you clear of the scenery. If you weren't you landed on and kicked out ballast. In effect it was only used for clearing relatively low obstacals such as hedges and bushes although it depended on how much power you had in hand. Of course you always did a power check before you started to ensure that you werent wasting you time.
The max performance T/O or running T/O as it seems to be called over here is on much use on a very flat, smooth area with plenty of room. It can get a little exciting in a Robbie if the ground is not smooth.
