I filled out the top of my bag with Gen 4s and haven't regretted it at all. Some of the best feeling fairway woods I've owned. The driver is great too, and going PXG saved me $500+ over TM, Calaway or Titleist. I was fitted between all four brands and they all performed more or less the same for me so it was a no brainer. I'm just a little bummed the GEN 5s came out 3 months after my purchase, because they do look nicer!
