If I may add something more, perhaps in line of what Mike was thinking when he stated ;
I like this idea, as I've stated above in how having Golfer attributes can make this work.
By having different Golfer Attributes, none of this will see the exact same shot from the tee or any part of the course. Putting may be something totally different, but the only usual benefit gained in watching another golfer putting, is seeing the break on a roll toward the cup. Knowing how hard to hit the putt isn't something that should become easier for the person closer to the hole, because you watched another golfer. On many golf games, we often gain benefits in this way seeing how to recreate the same shot from the previous golfer.
Perhaps a change from the above, still keeping in mind what Mike stated, is to remove the visuals of the shot details from other golfers. Maybe call it Tournament Mode, where no-one sees anything but the golfer swing and the result. No meters are displayed or power bars, therefore you may only gain a visual in how your opponent used a full swing or a three quarter.. but no specific marks on the swingometer.
I only wanted to add this extra comment to ensure those reading understood there may be many ways to introduce something they don't like, mainly because of the way they feel it's being introduced.
I'd be all for that Ian.
When playing either online with an opponent or with a CPU partner or recorded round, when the opponent is playing their shot, all you see is the player animation playing the shot, but with no swingmeter, club info etc.
