I spent some time tonight at the range with the Taylormade R9, Taylormade Burner and Cobra S2. I like the Taylormade R9 best.
I was testing with a 6 iron and was getting around 140 yards carry on average. That seems very short for what I see the pros do, but I understand it is more important to have consistency and knowing what club to dial in for a particular distance. Also, range balls are probably 10 yards less than actual good balls.
