Companies...so I'm torn. While it CAN be the shaft and logic says the part that changed is the culprit, it's entirely possible that the shaft itself is fine, but that other vibrations/etc can now be felt because it is less forgiving....bah, whatever. I know what you are saying though...if I put the other one back, I'd be fine. But that's not what I'm going for right now. I'm working on it.
