Haven't had the chance to play the new version yet as it's not out for Mac, but my main wish would be to try and create a game that's a little tougher than the current version if you're already in the process of re-creating it. The main problem is how easy it is to hit the sweet spot of the clubs (except for the 3W).
Driving should be A LOT more difficult. If you keep the simple "hit-the-ding" method for hitting balls, then every slight missed ding on the drive should have severe consequences and lead to the ball straying way more off line than it does right now.
As I don't think the simple hit-the-ding method will be reformed, I'd be in favour of putting all clubs' settings to the one that's currently in place for the 3W: much less consistence, even dings going way off-line etc.
Plus: Keep UEL or I'm out anyway ;)
