Had another shave with the MJ-90 last night. I think it's a no go right now. I did 3 passes with a feather blade. Tried every which angle. Extreme shallow and steep angles as well. No dice. Added a shim. Did 2 more passes. Did a ton of buffing. Barely made it to DFS. I've given this razor more than my usual amount of effort. Gonna save the head for someone that needs a really mild shaver. The handle is awesome. It'll get another head. I have a couple of NEWs that need handles. Sorry this one didn't work out. There are too many awesome razors to keep messing with this one.
