Last year, I had the Tourstage X-405 Driver. I have played the Epon Driver and now I play with ERC Hyper Driver (is a very expensive hobby!). While I love my ERC, it seems all my good drives start out with an extremely high trajectory. They do not baloon at all and overall, have a good roll when landing. However, I am wondering if this is a characteristic of a Japan driver and new technologies or is it possibly due to the wrong shaft. I think if I can lower the trajectory a little bit, I would get that little extra distance and roll. Also, do you reduce trajectory by getting a stiffer or heavier shaft?

I truly believe its as much the shaft and the characteristics of one swing as it is the head. In fact maybe more so. The shaft has a great deal to do with trajectory, but if one comes in with a steep swing, the ball will upshoot much more than a swing coming in much more level. My trajectories with the JDM equip are usually very boring and on the middle-low trajectory, especially when I'm swinging really well. I know when I swing someone else's domestic equip or using a demo, the trajectory is too high and usually balloons. Typically its because the shaft is too light and/or not stiff enough so I just overpower it. The shaft doesn't complement my swing. I use heavy shafts and with the fine materials and workmanship of the JDM stuff, my trajectories are just what I'm looking for, far out there and on a string.
