Upgrading an X-6 to X-6FC A few months ago I purchased an X-6. I chose the X-6 over the X-6FC (fixed clamps) because the online manual and specs stated I would be able to upgrade to the X-6FC. Well, I've been doing more stringing than I thought and decided to contact Gamma to find out what the deal is for the upgrade, keep in mind it would be as simple as screwing on two rails with the clamps. Gamma was very responsive with getting back to me but their answer was an upgrade is not available and when it does become available it would not be cost effective. Their advice was to get an X-6FC and sell the X-6. Am I nuts to think they're wrong for publishing the X-6 is upgradeable without having an upgrade available? Also, why would an upgrade be cost prohibitive when the difference between an X-6 and X-6FC is $170? I don't understand how it could cost them more to offer a separate upgrade when they would use the same production line. Needless to say I'm disappointed.
