I am more into soft pop and rnb stuff whereas as I have seen Kim mostly singing rock and some pop so I was wondering if ktva will be a faster road for me or I should use ssl method instead? Because ssl works pretty early on that sweet head voice .Thanks in advance

Of course I'm going to recommend KTVA because 1 it works for me and I've never tried anything else. 2 because the training gives you the choice of singing light R&B or hard rock. In the course Ken also states you can choose how to do the exercises depending on what your goals are.
