Seems like 250 carry should be more than enough.
However, on the flip side I had a somewhat bad experience with one of the optical launch monitors and cheaper radar units ($6000 system?). On the course, I was hitting about 40 yards further than the launch monitor reported, and the salesman recommended a senior/ladies flex. I did some experimenting on my own (using a prototype board with a 6-axis gyroscope/accelerometer), and found that the heavier the shaft the better. Based upon this data, I bought some steel DG X100 wood shafts. I had them put on an old TM Burner 1.0 driver, and with a relatively relaxed drive I was hitting about 10 to 20 yards further than before and much straighter. That's about 60 yards further than the club fitters told me I could hit.
So, the launch monitor told me that I was hitting 40 yards shorter than on the course with my old driver (Google verified), but I ended up using a shaft made for someone with a much faster swing and ended up hitting yet another 10 to 20 yards further than before. So, in this case I went completely the opposite of what the fitter(s) told me, and have better results.
BTW, none of these fitters had a Trakman.
What an extreme. Don't club fitters have to pass some type of test to get certified..? I realize there can be "opinions" about something like that, but to be that far off, makes me hesitant to even consult a club fitter.
