Comments:

Most of these are subjective naturally. Some may not be crazy about the crown as at address you can visibly see the mesh weaving, green lines and alignment aids. Head is fairly normal shaped though. Adjustability is consistent with what is out there on the market. The sound/feel will be very highly regarded i think. It’s kind of a muted thump. It gives feedback but is not overly loud, just a powerful thumping sound/feel. I liked this a lot

Comments:

Distance wise it’s the longest club i’ve ever tested. I gained around 15yds of carry versus my previous driver (which was around 3yrs old) with the same shaft playing the same length. I did not think that kind of gain was possible frankly. Launch was ideal, on trackman i had a few hits that were essentially perfect numbers for my swing speed. It’s a forgiving head but will not perform miracles, i hit some big drives that were slightly off center, but hits high/low on the face or serious mishits are going to end up in bad spots too. I do think it’s above average for forgiveness, however.

PROS:

Distance and feel are in my opinion and from what i have tested best in class. Feel is subjective but many good players like a muted thump sound and that’s what they’ll get here. Distance wise i gained a lot of yards without sacrificing control, I mean that kind of says it all

CONS:

If i had the choice in a perfect world, i’d like a blank crown. I think there’s supposed to be some tech with wind channeling/resistance or etc with the ridges in the crown, i didn’t see any SS gains. If we’re going into semantics the crown is a little busy. Also adjustability is about average. One of the directions has 1 degree of adjustability and the other has 2 i believe. Again not a big deal, some companies offer more.

Summary of My Experience with the Club

It performed better than I expected , it gave me yardage gains i didn’t think were possible in this market. Overall i think it’s a great driver that could give me tangible benefits in scoring (hitting 1-less club into greens for example) when struck well.
