I bought this board about 6 months ago (used, no dings, great shape, great price), and I've been getting grief from many of my w'surfing friends, "take that ugly thing off!", I haven't,,,,,,,, yet. I haven't decided, it will leave an ugly mess to clean up once I pull it off, but I do wish it wasn't on there.
Most rental fleets have them on, and I can easily see why, they do work very well, as well as not hiding any damage, it's a good design, about 5 cm thick. After 30+ years of w'surfing, I don't really need it, but maybe I'll remove it during the off season if I feel like spending hours with acetone scrubbing out the residue from the textured top, it won't be easy. I love this board BTW, one of the best I've ever had.
