This shaft is super light, very strong and the shape is amazing! I also love the flex of the iQ9, especially for inside shots playing box. It feels very similar to my Gen 5 (which is also a great shaft) and I really like the new graphics. I highly recommend this shaft for players who are ready to invest in a top of the line model. Please see my "cons" in order to understand why this shaft gets 4 stars instead of 5.Pros:
The set screw hole did not line up with my Maverik Optik head, so I had to fill the pre-drilled hole in the shaft with epoxy and then re-drill it. Otherwise, the holes would have been too close together to get a solid attachment point. I am not sure if there is a standard for the hole location on heads and shafts, but there should be. Otherwise, I would prefer this to come without a pre-drilled hole. Also, because of the shape of this shaft, it fits pretty loosely with most heads. You really need to wrap a piece of tape around the shaft underneath the head in order to prevent it from wobbling. These are minor issues, but could use improvement to make this the best shaft on the market.
