Okay in the world of drivers. I currently have a Callaway C4 driver while it looks cool and gets the job most of the time. I am interested in something new. I used to hit this club almost 285-300 yards consistently but now that I am 5 years older and fatter my club head speed has slowed down I assume. (I no longer spend 2 hours in a gym, career & family have hindered time) I generally hit it around 240-260 yards now. When I mishit the driver, 90% of the time it is off the toe so would a larger driver help that? The C4 is a 360cc head and I see new 400cc and 460cc heads. How much bigger is a 460 vs 360. I tried looking up a conversion table but nothing seemed to pan out. I know this is a jumbled mess of a post but if you can make sense of it please let me know your thoughts.
