I’ve been looking for several years and can not find it. So I ordered 2 SUL and 1 XUL. As far as I can tell an XUL is softer through the butt.....on my Palms Egeria anyway. Major Craft at one time sold XUL and SUL. Palms only has XUL and now Major Craft has done away with the XUL rating. I have seen some rods that have an XXUL rating. Hope to get an XXUL someday. Either rating you get you are fixing to have some fun....LOL.
