Indeed, and I often play from the yellows in bounce games, especially if in a mixed group to be more sociable. Last week one of my county team mates and I played off the yellows at duddingston and had a great game with the advantage that a few holes that are way too short from the Reds became much more interesting. The problem on many courses though is that a lack of women's par and SSS from those tees prevents us from accurately using handicaps either to compete with men or just to have a realistic idea of how well we scored. At a forum meet, for example, I might as well just donate my sweep money if I'm playing off yellow or white tees while still using the same handicap.... As I have done a few times.
I'm also aware of the extra time it takes when a group is split over different tees. All the things I might do on the tee while my PPs are playing have to wait until they have played and we move to the red tee. It definitely delays play.
I am quite new to this forum, but have clocked that you are female, how did you get on round Duddingston off the yellows?
