I guess it's that K Factor, but even though the stats are pretty much the same between the KPro Open and the nPro Open, the KPro Open feels a little more solid than the nPro, especially when playing against heavy hitters. Like the nPro, the KPro is light yet very stable. It's maneuverable at the net, good with the serves and holds it own on the baseline on both wings against anyone! I like the color scheme, even though most don't. If you liked the nPro Open and are looking to upgrade, the KPro Open is definitely the stick for you! – Joe, Newport News, VA
