The main differences between the Classic and Pro extension kits from CableMod are as follows:
- Cable Construction: Pro Series cables feature thicker wires, which provide a fuller and more robust appearance. Classic Series cables are assembled without merged terminals but do not have the extra thickness of the Pro Series.
- Cable Combs: Pro Series includes premium closed cable combs for a professional look, while Classic Series offers standard cable combs.
- Aesthetics: Pro Series offers a revamped color scheme and community-driven color combinations for a fresh look, whereas Classic Series maintains a more traditional aesthetic.
- Durability and Materials: Both series use durable nylon fibers, but the Pro Series emphasizes a more premium build quality.
