I have a Cleveland XLS Driver and i'm pretty happy with it, i'm hitting the ball further than I have ever hit it before, i've always been pretty straight but increased my distance from an average of 240 to 265. I see that there is a new driver by Cleveland called the XLS Monster and it is said to be 16% larger than the original XLS. Other than the size can someone tell me what the difference is in performance? I've looked for the difference in reviews but really cant find anything that describes the difference in performance.
