I agree with enduroxx!
I say mainlining is probley the best but probley the most challenging. (never done it but FUCK look at nug buckets results! That's my next grow)
FIM technique is pretty fun too, pretty much anyone can "fuck I miss" haha
But tru be told I like to LST because it gives you constant control over the plant and in my opinion it's better for the plant (in terms of vegging time and recovery) because your not chopping, or snapping the plant which can cause slowth in growth. Avoiding snapping or topping can help your plant grow quicker and eliminating precious time for vegging. Just my 99 cents
But whatever you decide to try I'm sure your plant will respond well and you will gain lots of experience.
Here's a pic of my current gsc and my version of LST training from day 3 of rooted clone. Extreme bondage No snapping no topping.
Veg for about 2 months going to three, about 20+ established tops. Cloned bottom 25%
