I talked with Todd at TCS the other day and asked him a few questions that have been brought up in here. There is no real difference with reserviors, piggy or remote. Just personal preference of looks. The only significance to long-travel is a better ride due to better geometry. The bodies are longer, but the stroke is the same. I did however notice that my long-travel are quadruple rate, adjustable. Elka and TCS have nothing in common. They used to share parts long ago, but TCS makes most parts in-house now. Hope this answers some questions.
