As our grind lines improve and we find that our old buffing methods (sticthed muslin wheels and buffing compounds of various grits)are washing away our progress what would be recommended to use next.

I tend to use a hand-rubbed finish on my knives, but when I polish a blade I typically go to 2000 grit to reduce buffing to a minimum. I use sewn muslin buffs and Green Chrome followed by No Scratch Pink. Both of these compounds are easy on grind lines. I am not sure if that is the type of answer you were looking for.
