It didn't have a Predator shaft when I saw the cue, and that would have been about 2000, give or take one or two. Bear in mind, at that period of time, guys hadn't largely gone to Predator shafts just yet, but that was to change shortly.
A bit of memory, the very first well-known tournament player I saw with a Predator shaft was Mike Davis, probably a little after that, playing in a tournament in Rockville, Maryland. That was the first-generation Predator shaft, which had a longer ferrule that later generations, but I could tell it was just a bit shorter than the standard one inch, so it did look different. The rest of course, is history, as a lot of guys went with Predator soon.
Doc, when I pass away, you may want to section my brain to see what kind of cue memories can be extracted.
