Save your money.
The customs being sold here at $400-$600 are way sweeter and have much higher value retention, that's just my two cents.
Isn't the upgrade for the predator cue just the difference between the 314 and the z while it means buying another shaft for the other cues? Not sure on that one but since I don't like piloted cues the economic factor is the only one that comes into play in my analysis, lol.
Good luck with your search whichever way you go!
