I only shoot in the 90s, but am decent enough with my wedges that I wished I had one. Poor off the tee is my weakest point, but I also suck at gauging distances. I played with a friend who has one, and I avoided at least three instances where my estimates using course markers and the lame skydroid gps app on my phone were off by 7 to 8 yards on pitch shots. Hit the green on all three.
Sure, $300 in lessons might be more beneficial, but three strokes are three strokes.
