I now have a bag full of Sub70 clubs. I am someone who is looking for easy to hit clubs. I am about a 20 handicap. I started with a Sub70 5 wood (939X) last year and recently bought their game improvement irons (799) and a driver (849D). I have not had much good weather to test, but the times I did get out, the irons performed well and the driver was phenomenal, i.e. easy to hit straight. I would definitely consider these better than the Ping irons that Club Champion fit me into several years back. And the driver is the easiest to hit I have ever had and that includes Ping, Callaway, Wilson, Mizuno, etc. I'll keep you posted on how they work out.
And yes, as of now, I am a Sub70 Fanboy!
