I've been using Game Golf since 2016. According to that the highest FIR% I had for any driver I gamed for at least a few rounds was the PXG 0811XF Gen 2 14* with FGS+ Electric shaft - 81% FIR.
Honorable mention - M3 FGS+ shaft - 74% FIR.
From memory though I had a Ping G30 with Tour 80 shaft that played at 44.25". I would choke down on tight holes a couple inches and play a half swing "bunt drive" that was a fairway finder if I needed it.
Driver: '16 M2 thing was accurate and scary long. However died on a range with a massive crack.
I would say if I absolutely need to hit a fairway and the hole isnt dreadfully long I would probably either swing easy with driver or step down to 3 or 5 wood or 3 iron depending on length of hole and where I need to place the ball.
My present, the G400 Max. I prefer to hit it over any club on par 4s and 5s.
Admittedly, from the blue tees, it does get me in trouble sometimes as I can hit through a couple of fairways into trouble if I don't throttle it back.
But I LOVE hitting the darn thing!!
Runner up goes to the original Epic. Loved than one too but not as accurate as the G400 Max.
Next was an old Macgregor MacTec NVG 435cc driver. Smashed that thing, so very accurate for me. But the face caved, welds for the cup-face gave out.
My Callaway X2 Hot 12.5* 2Deep fairway wood. It’s still in my bag after 7 years and owning about 20 other fairways woods/mini drivers. I bought and tried to like the Taylormade Original One and their M5 3 Wood this summer for a couple months but the old X2 Hot is back in the bag.
