nhwr and mbm-actually this is more the kind of answer I was looking for.
I was having this discussion with someone and I didnât really have the answers so this is why I am asking.
I know for sure, the goal is to have a supple horse with a lifted back and lifted base of the neck.
Part of the reason I am asking is I recently watched a video of a trainer that is NH with a strong âFrenchâ influence
The horses were soâŠSOFT and SUPPLEâŠthey looked like ballerinasâŠbut what caught my eye is how LIGHT the contact was-the loosest was a slight drape of the rein-so the contact was simply the weight of the rein.
At times she did take a very small âfeelâ but still quite light by most standards I would think.
The focus was heavily on lateral work.
BUT when I have asked others they insist that no contact=no âbowâ=no ability to really âengageâ the topline and base of the neck, for lack of a better way of putting it.
I have also read material from Dr Deb and she really focuses more on suppleness and lateral moves for engaging the base of the neck.
Anyway, providing for the reason behind my question may help see why I am asking.
I am not wondering which WAY is better-rather if this neck development and posture CAN be achieved (CAN a horse be using his back properly) with a contact SO light it appears only as a soft feel with a drape in the rein being the âreward or releaseâ as opposed to-CONTACT with the release being lighter contact.
I am not looking for high level dressage moves in correct fashion for competition, rather just to strengthen and properly develop a horse for his health 
I am never going to be a formal dressage rider that progresses to a double bridle-so am not wondering about that level of finesseâŠsimply correct biomechanical movement.
I have a hunter background and do have as of the last several years a high level of comfort and appreciation for my natural horsemanship training-I just was to be very sure I am on a good road to developing my horses physically.
So again, is there a difference in the end result (horse moving over his topline)-I understand there is not-
BUT I do understand there is a difference in HOW each thought or method gets there.
I just was most curious if at some point if a more âfrench conceptâ would eventually NEED more connection or if the suppling and lateral moves, encouraging self carriage earlier on would âget the job done.â
Hopefully that makes it more clear why I was asking and where my question was coming from!
