I love the FIM and do it to all of my plants. Unloike most, I like to do it at about 2 weeks into flower or right when the small budding nodes begin to form.

Yes the placement of the cut is essential. It is important to cut right through the bud node while also clipping off the smaller leaves right around it. i like to just grab the tip of the bud and cut through the leaves and the node. It does cause the cola to grow out a lot causing it to get much bigger while getting a 2 or 3 headed cola at the tip.
