The Timeless for me was much smoother than the Karve but I never tried anything below a c plate. I sold my .68 because it was to mild for me. I love the titanium 95 because I also have sensitive skin but find it better for me to use a more efficient razor so it takes less strokes so I get less irritation. Definitely work on your technique as that will help you tremendously.
