Someday I might try not topping one... I've never trained one as much as I am planning on training the group I'm growing now. Actually, since I've only grown autos outdoors, I've never really trained them at all. I have done some sort-of-mainlining with indoor photos during veg, but that's it (other than scrogging, which I've done indoors and outdoors). And they were all topped.
I'm two days away from starting LST'ing my plants (hopefully like you did), and I'm kind of nervous. Never bent a plant over like that before. The training I've done was with plants topped after the fourth node, so all I was doing was spreading out the main 8 branches.
I'm still figuring out how much of what I know from photos also works for autos.
