    What's a "charis table"?

    Off-hand, the hollow rods are probably cheaper and they're undoubtedly lighter. When you're designing a product, you're into engineering, and engineering involves lots of trade-offs, especially at the top or system level. Ultimately, there are three categories: good, fast, and cheap. You can have at most two of those in any product, with rare exceptions.

    My 4000th post!

    My previous comment still stands. It's all an engineering decision. Does that make sense?
