I had to wait until mid-August of last year for the second run of KISS Pro, since the first one in June sold out quickly.
It was on location for 10 months in the same spot, and consistently earned well, with a few spikes, and not really any drop off, which really surprised me. I would have liked to have kept it there for a few more months, as it would have paid for itself! However, GB arrived, and it had to leave.
My basis of it being my best earning pin, is after its initial 9-12 months from NIB. Nothing else I have has earned that much, that quickly. Other pins (Star Trek, The Walking Dead) have comparable numbers, but that is after about 18 months, not 12.
Behind those, but still earned okay:
For what it's worth, an operator in the Bay Area I know has also had similar findings as I did for KISS Pro.
