First post, English not the first language please be patient…
My experience with an LX600, is this:
:: Feeding ::
Some medias simply don't work, they have feeding problems, this problem gets worse the smaller width they are.
Ex: Oracal 3164 (42" Not good) (63" Ok) with the same settings, i can't print the smaller width regardless what setting I use.
This problem can't be solved with the advance calibration! when you see a misregistration on the same head color (ex. pure Magenta, pure K), its a feeding problem.
I found these 3M medias good to print regardless of their width, and very compatible with each other settings wise.

IJ40
IJ1229
IJ170
IJ380
I'm not a 3M sales man or affiliate with them, its just one brand of media I found to be good to print.
CDIESEL, mentioned "Every once-in-awhile", this is unacceptable to me, when a media is not stable the "once in a while" is a serious problem, when you do small prints ( more grain/lost detail), and in bigger prints you might notice color banding. The problem is the same i'm using the size to differentiate viewing distances
:: Dynamic Color Registration ::
On the LX600 I only have 2 points, A & B.
The problem is they both influence each other, so with the "one shot" calibration process of the printer it simply doesn't work.
What I did was create a similar registration file, and after getting all the other settings sorted out printed the file multiple times until the registration was OK, you can't achieve a perfect registration, it "floats" during the print length, but I found good and stable settings can be achieved.
I hope this helps you get started.

No one has problems with the fragility of the inks when scratched? Here, we laminate most of our prints.
