Barneys farm, violator kush. 60cm tall but very bushy at 60cm wide, nodes less than a cm apart. Predictable, forgiving of temps and EC and clones easily. Put mine through hell and still almost made a g/w. Only problem is price (expensive) and odour control. It effin stinks. Also not a smooth smoke. More of a lung-buster.
Best bet for keeping height down though is scrogging.
