Hi Erick,I guess its how you define "connection" and "resistance" and how the skills of controlling someone are cultivated.
There are many paths, no doubt.

IMHO, culitvating resistance in the beginning can be a good thing, as most people aren't sensitive right off the bat to really know where their uke's force and intent is _really_ going.
To the extent that nage or uke needs enough to feel above their threshhold, I agree. Beyond that, additional force, I think, is counterproductive. A fine balance must be struck and always try to keep them teetering at the edge of the sensation they are feeling for. If you don't do that and keep the dynamic toward ever less "firm" (apart from atemi) then the dynamic naturally tends toward the other gradient -- the testerone-competitive monster tends to jump in and starts the "me-bad" dynamic. It is not as helpful to development of good musubi connection.

Can you define "juji" and its application?
Several of O-Sensei's Doka mention it, one even calls the art "jūjido." Juuji or jūji ( 十字 ) is the cross-shape or sign of the cross (for those so inclined). It is a symbol, a physical principle, a template for technique and spiritual basis for contemplation of practice.

As kanji, 十 juu not only means "cross" and "ten" but also "whole" or "complete." As a symbolic image in Japan, the horizontal symbolizes Earth, and the vertical symbolizes Heaven, i.e. -- tenchi, the union of heaven and earth at the center. It is another means of depicting in-yo with the dynamic elements of the opposed eight powers (bagua) built in.

As a physical principle, juji depicts the action of perpendicular component forces. In motion in a linear plane, perpendicular forces resolve to linear diagonal forces in proportion to magnitude of the two components. Judo in contrast focuses on using or creating an offsetting pair of opposed forces (a couple) to initiate rotation. In an already rotational or vibrational frame, force perpendicular to the rotational or vibrational plane have resulting perpendicular forces that are not linear, because of the inherent angular momentum, the resultant force depends on where along the radius of rotation/vibration the output is taken. The fact of that momentum also allows the sytem to absorb a great deal of energy withou out readily perceptible change.

Juji in aikido presupposes that there is an existing rotational or vibrational energy to receive and gyroscopically transform a single input force into perpendicular output at a variable scale of radial amplification. That vibration or energy is ki no kokyu, or if you prefer the technical description, the physical application of the principle of virtual work on an instantaneously and infintesimally rotating body (at each joint rotational articualtion in turn and ultlimately at the collective rotational center of mass (tanden).

As a template for technique, heaven and earth are joined statically by their intersection at the center, and thus the center is arrived at by moving directly along the line. The conduit for kokyu tanden is established by feeling of that angle "lock" where the components of force are all cancelled in one dimension, leaving a complete freedom of movement there. The vertical dimension and the horizontal dimension of the figure are also joined dynamically by the fact that one becomes the other by simple rotation. Thus, the center is arrived at by spiral motion. The proof is left as an exercise for the class ...

As a spiritual contemplation, well, here you go:
