JT,
Wouldn't you agree that physical deceptions such as early bunkers etc are only a deception one time for most players? So I don't know ow you really deceive yardage wise now that rangefinders are here. But tight grass slopes that look to not be an issue are one way to play with guy's minds in the same way as early bunkers etc. For instance, a tight collection area that takes the ball to a bunker maybe 15 yards away and from the fairway the bunker looks to not be an issue at all. Or a wide fairway with a subtle slope on one side leading to a creek, pond etc. Yet if the same area was just protected by a normal bunker the golfer would just think "bunker" instead of ow close can I hit it....
AND if still not satisfied take some of the little prisms and place them in trees and bushes around the greens at you course and the rangefinder will never know if he picked up the correct yardage...
