I'm presently assembling a Pro 4824 and upgrading to linear rail. I've been delayed on progress this past week due to minor surgery. That gave me time to think and plan several items including the control cable routing & attachment. I'm trying to decide on leaving the cables loose in track chain, bundling cables, cables un-bundled but attached to chain with cable ties or cables bundled and attached to chain. Hopefully past builders can help me decide which method is best or the method you used.
