I'm going to have to try the E5. I'm using the E6 right now, but it just doesn't give me the control I like around the green. Excellent length, but not enough spin, even on full approaches with 8 or 9 iron. My favorite ball is the Pro V1x, but I just can't see paying the exhorbitant price that Titleist asks for them. It sounds like the E5 is going to be more like what I'm looking for.
