I wouldn't worry too much about what is natural in terms of the branch growth honestly. I used to get kind of hung up on that and I think I just wasted plant resources. Unless you're going to reveg the plant. In that case, keeping some of that larf growing down there is vital.
For FIM I have tried pinching, but I think I got the very best results by using a sterilized pair of nail scissors. Cutting about 80% or so of the apex growth tip off leaves just enough of it that it doesn't die, but temporarily forces the plant to redirect its distribution of auxins. The wildest branching I ever got was a combination of FIM and application of artificial cytokinin(Bonide Blossom Set Spray). The cut resulted in about 16 branches forming instead of the usual 2 from a conventional topping. You'll undoubtedly hear arguments for and against use of hormones though. Personally I stopped bothering because FIM was already producing plenty of canopy without it, but it certainly can give you some wild branching if that fits your needs.
