Well it looks like you found a hewing position that really works for you--more power to you, and by all means please don't let any thing that I say change what you are doing--
It really is challenging to say the least to try and teach a common group hewing, knowing full well that some in front of you might not be able to adapt to the norm when hewing positions come up for discussion
It would be nice to have someone speak up on how they handle this situation
