I also have flexwatt but have given thought to switching it out for cable. The reason is simple. When you clean the body of the rack (monthly) I spray disinfectant into each level the instructions on all disinfectants I have ever used are quite clear. Saturate the area and wait for the correct contact time (10-30 min depending) . Liquid and flexwatt are not very good together unless you have used waterproof connections. Cable is water resistant flexwatt is not usually. Racks are hard enough to clean the additional effort in dealing with flexwatt and liquid just adds more grief to an ornery task.
