My best advise is not to COIL them into small bundles. Bending the cables will, over time, cause the insulation inside to crack and then all hell breaks loose. I loop them in large circles and then use either cable ties or clamps to keep them during transit. Other than that, I don't fix them, I chuck them in the garbage and get new ones. Don't want to chance static on a 3000.00 keyboard with a 16.00 cable!
