Following below is a post I recently made on another thread but it applies here, too:
My home course has back tees with a rating/slope of 73.3/134 and I shoot in the upper 70s, giving me a differential of about 3 - 5 for handicap purposes. One day, I randomly met a single on the 2nd tee who was playing the next set of tees forward from the back, so I moved up and joined him for a friendly round. The next set of tees forward are at 69.8/125. I therefore should shoot 3-4 strokes lower from these tees, and in fact, I did so that day, carding a 73.
The reason I am boring all of you with these numbers is to illustrate a point: I had a lot more fun playing from the shorter/easier tees than I would have thought. Shorter irons hit into greens, a few lay-up tee shots vs. the back-tee drivers, etc. It was lots of fun and it opened my eyes to the golfer I had unconsciously become: play it all the way back no matter what!
I enjoyed shooting a lower score despite the easier tees being played. I will not play every round from forward, but it sure was fun when I did it. As an aside, I was playing with only 7 clubs (selected by me in the parking lot based on the anticipated yardages into a few greens) and my planning got totally screwed up when i moved up a set! It still was lots of fun, and that's what it is all about.
