I have played with one for the last few months (Predator built a prototype especially for me ) and LOVE it. It appears faster than any cue I have broken with and still has the accuracy of the standard 314 shaft.
We just got our first shipment this afternoon and will be shipping them to our customers on Tuesday. So, I expect lots of feedback from them in the next couple of weeks.
We will also be testing the cues (several of them) on our robot and comparing it to other break cues and posting the results on our website in the next week or so.
