First impressions:
Can the trace line behind the ball be turned off in the full game, seems unrealistic (to those of us who never used the turbo button in 09).
Rain just seemed a visual thing with no effect on the fairway or green.
When raining having spectators in their t-shirts and shorts was weird, any chance of someone drawing up some umbrellas or raincoats, same with more variation in spectators, seems there is a lot of incest going on.

Liked the challenge mode, well done for making it remember your last club and shot aim when retrying a failed drive or putt.
Think I liked the newer putting mechanic better as well.
Cheers
