I have almost all Nike clubs right now. I had Acuity irons from Dick's that worked ok, but I wanted some of my own (they're my dad's), so I went to Golf Galaxy and tried some stuff. They had a Nike Slingshot steel shaft set for $299. I really liked the feel of these compared to the others, I hit well with them, and I liked the way they looked both aesthetically and at address. Plus I've always like Nike stuff. From football to shoes, Nike's been a favorite of mine since I was a kid. So I picked up the set in June, and I've loved them. I did need a driver, though, since the driver from the old set was beheaded somehow ... I went back to Golf Galaxy and they had a Nike Ignite 460cc for $31.99. Needed a new grip, but the head was in great condition, and it has a Graffalloy Blue 65 shaft on it, and it's treated me well. I didn't find anything else that nice at that price, so I grabbed it. I also upgraded my putter to a Nike Method Core... again, it just felt good, and I hit better with it than the Odyssey I was also looking at. The Odyssey had more weight, and I found myself over-doing most putts.
So that's a Nike driver, hybrid, irons, and putter. My SW, 3, and 5 wood are still Acuity, so they still need upgrading (I hate the wedge, and the woods are kind of "bleh"). Who knows, maybe Nike will come through for me again.
