I had the graphite series 6 for 2 years and decided to switch to silver SS 2 years ago. After a couple months the silver looked worse than my graphite did after 2 years. I’ve polished it with never dull and capecod clothes and it gets the smaller scratches out but deeper scratches I can’t seem to remove. It does look good for a short time after I polish it but I don’t have time to polish it every 1-2 months. I really regret not getting the graphite last time. Looking forward to going back to graphite for series 10. Even if the upgrades aren’t that major I will upgrade just to get rid of the silver.
