I started using LST a lot recently and feel i have effected a efficient method. The only problem is yes, the drooping. I also lollipop and this time I went over board on lollipooping so I have to tie every branch up.
but to answer your question, besides those few disadvantages LSTing is definitely a way to go if you are worried about spacing of nodes and height. Yields can be very satisfying. Just stand by with some sticks and string
