I have hovered around 99-101 mph swing speed with most driver shafts thoughout the years. I have always use butt soft stiff mid and stiff tip shafts (latest is Tensei Pro White 60 stiff) with G400 LST 10 degree opened to most fade down to 8.6? So I hit the new Callaway Epic Flash SZ 9 degree head and have it in all fade bias weight. I was using the stock Project X EvenFlow Green 55 Stiff 6.0 shaft. This shaft felt amazing in that I could feel the club load and I could flex it. I don't usually get this as I play more boardier type shafts. Anyhow, I was getting 106-108 mph with this setup. I was launching it around 11 degrees and was getting a slight draw with this setup. Unfortunately, it was spinning around 4400 rpms. I tend it hit down on it and from the inside pretty aggressively. I tried other shafts and swing speed went back to around 100 and didn't load or feel the same. They don't offer and X-flex in this shaft and I doubt tipping it would drop 2000 rpms. I'm not sure if the flash sz head is lighter or this is a low kick point shaft but loved the feel. Any suggestions? Happy Sunday!!
