I can't compare to the X as I only tried the F and M speeds...I will say that there is too much draw bias for my taste in the F and it launches high even with the upgraded NV 75s shaft...I changed my ball position (farther back in the stance) and have found heaven in trajectory and distance...my only shot however is a draw as I find it difficult to contol a fade with this club...lately I have found it difficult to control fade with all my clubs so it has me thinking that it is me rather than the club...suprisingly I hit my old driver R540xd better now that I've gotten this club, and now also hit the old driver with a draw, although I am able to fade with a degree of control...if your swing is fairly decent I would go for the X speed...
