Re: New Pro V Balls from Titleist?
Interesting question. Do you give something a brand new name, or keep the old one? Not many golf companies go for the latter. Callaway's Big Bertha irons are one example (2002, 2004, 2006 versions are different, but same basic name), Cleveland's Launcher 460 is another (2004, 2006 versions).
As someone else pointed out, Titleist is already on the second generation of the Pro V1 and the only outward visual difference is a different sidestamp and the some copy on the packaging saying they're new and improved. Callaway's doing the same thing this year with the "Improved" HX Tour and HX Tour 56.
I say stay with Pro V1 and V1x. It's a bit more like automotive nomenclature. A Toyota Camry is a Camry no matter what changes come, you just differentiate them by model year. I don't think anyone is going to not buy the next-generation version of the best-selling ball in golf because of the name. I'd play a 2007 Titleist Pro V1x regardless.
Besides, there are too many bad product names out there already. Let's not create any new ones.
