Back combing is ok, but if you want to use a starter method, TnR is much gentler. Back combing tends to rip out s bunch of hairs and can hurt quite a bit. Plus, if done too close to the scalp, will be uncomfortable and can make them poke out at all sorts of angles. TnR is easier on your scalp and has roughly the same effect.
Neglect is the most healthy method. But it's not for everyone. I wish I used it, but didn't. At this point, my locks are old enough that I can't ever see myself cutting them off and starting over. So I'm stuck.
Have you checked out the dreaducation link up top?
No starter method creates locks. All any of them do is help define sections. So don't be afraid as they start to fall apart in the first few months. It's natural. Unlike neglect where pretty much all you see is forward progress, starter methods have a 1 step forward 2 steps back method of forming. Everyone who used one has gone through it. And they are all willing to share their stories and picture of where they are at. check some of the timelines out and see where you will be at in the future. It's a good way to gauge your progress
