I'm currently playing with a G15 9 degree with Serrano shaft which launches the ball too high for my taste. I'm looking at shafts to bring down the flight, and as I can't get a prolaunch red for love nor money I am probably going to get the two shafts listed in the title.
From what I've read the Penley is the one for lowering the flight but the GD YS6 has excellent reviews also. Has anyone any experience with either of these? I've also considered a Aldila NV but I thought the Serrano was the latest version of that one. The pink one would have looked good though!
