I haven't read all the posts in this thread but I am curious: Was your scratches in your new m6 with kentmere film? I ask because I know you shoot it a lot. Anecdotally, my M5 will put some scratches on kentmere but not with other kodak or ilford products. This led me to believe kentmere was just a softer emulsion. Anyways, no excuse for your new, spendy Leica to be scratching ANY film but was curious if it was film dependent. Granted, my M5 is not your M6 and the M5 is long in the tooth so I just deal with it's specific oddity of laying the occasional scratch on K100/400 by loading other films into it.
