Re: do a technique or flow into one?
Not only that, but it assumes you can throw a decent left hook. The trouble with Alberto's approach is that it assumes anything that flows out of you naturally is any good when you're a beginner. It's not. The beginner's first task is to learn to move in ways you find profoundly unnatural, because you've never moved that way before. That's why kata exists.
Once you've made the previously-unnatural movement patterns natural, then maybe you can get creative with them.
