John:  For the 2008 season you will have the option of which system you wish to use. Of course, this depends on the boat being used. If a 2008 Nautique, you have no choice - it's ZO. But a 2007 Nautique could have Star Gazer as well as PP Classic. Malibu will have Star Gazer and PP Classic. MC will have ZO, Star Gazer and PP Classic. Here's the weird part: given you have a choice, you will be able to select which version for EACH PASS if you so desire. This is a nightmare for us drivers and makes little sense as a skier but that is the way the rule is written. The intent is to give everyone ample opportunity to ski behind the new systems as much as possible. In the end, I think the PP Star Gazer and PP Classic will feel so similar that no one will notice and will elect one or the other. As for ZO vs PP Star Gazer, only time will tell.  jhd
