I'm interested in building a flexy rack, but after looking on this board, all the racks I see look like the salamander archetype system with threaded rods. Are there other options for the posts? I just don't like the look of threaded rods and would prefer the more "finished" look of, say, the salamander synergy posts. Is it possible to build something in that vein for reasonable cost? I'd love to build something along the lines of synergy 30 or 40, and have access to most if not all the tools I think I'd need. Thanks in advance for any suggestions.
