Nick, you should hang some Christmas lights off that bitch and put her in the living room window. She looks prettier then a lot of decorated, dead pine trees I've seen.
LST is a very plant friendly way of encouraging bushiness. After topping or even super-cropping the plant goes through a stress/recovery period. With LST the recovery time is almost null so growing times are barely effected.
Sometimes I'll do nothing but some serious LST on a plant, continually pulling the plant open on itself on every new shoot until I get a decent spread then let it grow untrained.
