And you've hit the important part...carry distance. I went from 280 average to 250 average total distance in one day. How? I moved from Las Vegas to Florida, at sea level with wet fairways and no roll. That's why all these claims of high handicappers easily averaging 300+ yards have to be taken with a huge grain of salt.
This for sure. Most days on the courses I normally play most of my drives will go at least 270 and many will end up in the 290-300 range, but put me on a course with soft fairways and minimal roll out and I remember that really I just carry in the 250s, maybe in the 260s on my absolute BEST drives, and I'm just used to hard SoCal muni fairways baked in the sun and minimally watered that give 40 yards of rollout so I think I'm a 280s or 290s hitter instead of a 260s or 270s hitter :)
