IMHO: the CB Hex bar Linkage, properly upgraded with Heim bearings on the ends, rather than the quickly wearing ball-in-socket that it comes with and adjusted properly to your carbs (and Commander Pip is a whiz at this) can provide you with a pretty damn good linkage system. As good as a "Sync-Link"? Maybe a tad less but I personally feel that most people would never notice any difference if they were both set up properly. Stan might, but he has a sensitive tush to that sort of thing.
