I am a big fan of LST, but he is I think 4 weeks into flower? I don't recommend any training unless ABSOLUTELY necessary. I had to lst some plants week 3-4 in flower due to 3x stretch and they are going on their 8th week of flower with the end not for another 3 weeks atleast on an 8 week strain. Training will increase your flower time and you are increasing the chance of hermies.

I have never super-cropped, only topped and LSTed.

I am by no means an expert, just information based on my personal experience.
