I have done both and it really depends on your height limit...if height is a problem I would super crop...if height is not a problem then i would top them ...they both have their benefits i think its really a personal choice
LST all the way..no stunting of new growth, but lower branches still come up to form tops. Only con is the new growth doesnt split like when you top it.
all the techniques are pretty simple...FIM just pinch off the newest top or use sharp clean scissors and cut it off...it pretty simple...or you can top and use the cutting for clones
