Milt,
Probably better to leave that question to one of the site's TP fraternity who is in the thick of such things.
Such exposure as I have had to testing has seen instinctive rudder reaction permitted although thrust changes post 42 have included the delay.
Thinking back to some specific runway deviation testing in years past ... a delay in rudder application would have been considerably more than just interesting ... I still have some videos taken (with BIG lenses) from the far end of the runway ... quite sobering to see airliners dancing left and right like a dainty ballerina ... even have a picture of the illustrious Red ambling across the runway a mile or two from the camera.
By the way, I am in your town periodically .. if you see it as appropriate, do let me know a contact and we can catch up for a well-deserved quiet one or three sometime ...
