Anyone tested R7 MAX, XR-05, or XR-05 CTI?

[jlauber]

I am considering ordering a new driver from TSG, but I was hoping that perhaps some of you may have tested some of the so-called "hot" drivers, such as the R7 MAX, XR-05, XR-05 Special Ed, or CTI. I also recall reading a previous thread somewhere here about the Ping G2 having a higher ball-speed. I would appreciate any feedback, especially if it involves a launch-monitor. I realize that shaft weight, length, and flex also play an important role, as does loft, so much of the feedback maybe subjective. I probably have a 110-115 ss with 45" drivers, and have hit 125 mph with a 51" driver. Curiously, though, I have had much more success with lighter shafts (as low as 46 gr.). Therefore I am considering the (expensive) Mitsu Trixx Super-Magic, (43 gr. at 47"), built to a final length of around 48-49". I have had a problem with cracking heads, so I am a little leery about these ultra-thin, high-COR drivers. Anyway, I will welcome any of your data or experiences.
