If the forums can help the instructors income, then the reverse is true also.
Just to clarify, when instructing, you want to teach a repeatable stroke. No elbow drop is by far the easiest way to a repeatable stroke. I don't know of any of the instructors that say you absolutely should not drop the elbow AFTER contact witht he cb. But, depsite some very good players, such as Mike Massey saying the opposite, it is not necessary to drop the elbow after contact because it is doing absoulutely nothing for the stroke. So, why drop it at all? When you are learning, dropping it after contact can easily transfer to dropping it just before contact. Thus, screwing up the stroke.
You yourself have stated that the top players mostly don't drop the elbow until after contact. That is what is taught. Not dropping at all just makes it easier to learn. Once again, hence, talking out your arse on this one.:wink:
