Quick review from playing 9 holes
Looks: It looks great in my opinion. I don't know if its the color combo or what but it looks a bit smaller than my 2016 m1 and has a stealth look to it.
It terms of how it played - taking only about 6 hits with it, I cannot give a comprehensive review but I can say that it definitely does what it is supposed to do. I normally can play my m1 2016 1 or 2 notches towards the closed setting on the TM adapter without fearing the hook as my normal good swing is a baby fade. With the M4 d-type, I had the loft set to the -2 setting and still could not hit it straight or right - it just wanted to go left. It was definitely weird aiming off the fairway on the right. All in all, if you hit nothing but slices, grab a d-type driver. Unfortunately (or fortunately i guess) i was near the centre of the clubface for all my hits so I could not test the twist face. In terms of distance - I can't really say as it was a bit of a windy day and the fairways were soft so can't truly gauge distance and roll. Out of 6 drives, 2 were hit low on the face resulting in a low draws, one was hit very high (almost a skyball) that went fairly straight and the other 3 were hit in the middle resulting in 1 good draw and 2 draws that were good only because I aimed way right. If I aimed down the middle these two hits would have certainly been off the fairway.
Overall, this club can cure a slice. I generally have a very hard time hitting a draw and this club made it easy. The problem for me is that it would also make it easy to hook it OB left, even if I aimed way right as one of my swing flaws is a pull and if I played this club it would be a pull-hook into the woods. I have a buddy demo-ing it at the moment - we'll see if he experiences the same thing on course when we play next.
