There are 2 problems with the factory arrangement. First overcoming the increased friction of getting the fairly long length of tambour to load. Second overcoming the flexibility of the long length of tambour itself without it wanting to buckle. What I did was this: I cut the tambour into 2 equal shorter pieces and added a pair of tambour handles on the second piece. Now I only have to worry about getting half the tambour rolled on the spiral. The second piece just slides flat to the left or right. Also if I need something from the cabinet on the aft side I don't have to roll away the whole tambour, only one section. If someone wanted to spend more time than I did they could also add a second spiral storage on the left side of the cabinet.
