That would be fine for the OP as long as he was shooting like Jerry Miculek. As long as he is not shooting that well, he needs to be looking for ways to improve his performance (unless he is satisfied shooting low-left).
Also, I’m skeptical about doing something a certain way because it’s “natural.” Sometimes one's instinctive reaction is not the correct response. In fact, it seems that one element of training and practice is to overcome instinctive reaction and to learn to automatically do instead what is most appropriate.
For example, when driving a car, one's instinctive reaction in the event of a skid is to apply the brakes. We know that is the wrong thing to do; and so, if one is lucky enough to get some training in high speed driving, one learns to stay off the brake, turn into the skid and, under some circumstances, even gently apply some throttle. I remember my first time driving a Formula Ford through Turn 8 at Laguna Seca -- a left-right downhill "S" turn. When hitting the apex of the first half of the turn, you can't see the track. My "instinct" said to back off the throttle. But of course, backing off the throttle under side loading while going downhill is a good way to lose the back end and spin.
Many of the more complex tasks we come to do without conscious thought aren't really instinctive or intuitive; they are, rather, reflexive. They are not natural, innate responses we are born with. Rather, they are habitual responses developed and conditioned by training and practice. It is, after all, natural to defecate in one's pants.
