Swing is a bit different these days vs. in the heyday of clubmaking so I'm longer now. 3 stick out for modern drivers-
Ping G LS Tec 10.5 (NV 85) hands down the longest.
Cobra f6 10.5, no slouch, man did I have a good run with it. Ugly duckling though (the footprint is like a pancake, shallow face). Also with an NV 85. Forgiving, easy to hit, straight.
16 M2. As long as the f6, but I was no where near as consistent with it. Fuji Motore Speeder 8.3. thought this thing was gonna outshine everything, looked good, felt good, taller face height....looks like it wants to be hit. Should do it justice and find a nv 85 for it. Side note I could not consistently fade it which is a go to for me.
Old school....3 stand out-
Db455 vs339 - probably the longest....no business playing that shaft
Snake Eyes python XL UST v2 75 HL - consistent like the f6.....first stretched out driver I played
Dynacraft Avatar xMOI prolaunch blue 65.....didn't think I'd come close to the Python XL, but this combo did. Neck and neck in fact.... but the XL sound/feel was superior.
Honorable mention to ct250 and the dynacraft
avatar inversion for old school. Ct 250 sound and feel good, inversion not so much.
