I have owned a set of these Acers for a few years now. I purchased the heads and installed graphite shafts. These heads did not seem to like graphite shafts. There was no feel. They were inconsistent... Almost no performance. After installing and reinstalling a few different shafts, I happened upon a Precision Microtaper combination that is an sbsolute dream. They are not exceptionally long, but they are very easy to hit and they are deadly accurate. This is my club now. I just hope I don't lose one as they are very difficult to find.
