I'm just trying to find out what replaced the Callaway HX Hot ball. Seems they came out around 2006/2007. I contacted Callaway but no reply yet so I though someone here might be in the know. Played an entire round recently with one I found in my bag. Despite the cover being a bit eaten up by the end of 18, it was the most feel and control I've had with a golf ball. I'd like to play Sunday with whatever is its equivalent.
