I have a NIB Original Inferno, box information says 15.98 lbs, 2.3 oz top weight, and 4 - 5.5" pin out.I have checked the pin out, it's just a little less than 5".  I have not checked the accuracy of the cg location or the top weight, but will be glad to do so if a bidder asks.  Serial number is HR13244, with that wonderful "MADE IN USA" immediately below the serial number.  This combination of top weight and pin out can be used with most layouts but may require a balance hole.  To lay it out without a balance hole the pin location will have to be well above the finger holes.  

I'm going to put this ball up for bids, minimum bid is $230, which includes shipping via UPS, payment by PayPal only.  If you want insurance that will be extra.  Bids will be accepted by PM only, it will be fine if you post your bid here for others to see, but PM me to have it accepted.  The auction will end at 11:00 am CDT next Thursday, September 10.  I will ship the ball, double boxed, within two business days of receiving notification that PayPal has authorized payment.
I will update the status of the high bid at least daily.  If no bids of $230+ are received I'm going to drill it for myself.  --  JohnP

You're right, 16 lb is not as popular, but it's what I've got.  Oh, well, if it won't bring $230 I've wanted one in my bag for a long time.  I'm just a little afraid it will be too aggressive for my combination of speed and revs.  --  JohnP

Less than an hour to go.  No bids, so it looks like I'll be drilling it for myself.  --  JohnP
