I own the TS3 and TS2 and started with the TS3 being my gamer and then went with the TS2. Today I had the chance to test the F9 and the M5 and the Flash driver. I used a TP5X ball but the shafts were all over the place but the results were surprisingly close....I found the F9 to have the highest ball speed but also the least forgiveness I terms of dispersion. The M5 had amazing speed all over the face and shots that felt bad went almost as far as pured shots.....Finally the Flash, I could not make heads or tails of this driver, it just didn't work for me, I just couldn't put a decent swing on it....maybe it was the swing weight or the shaft profile. Compared with my TS2, the F9 was slightly longer and had a faster ball speed, it definitely launched the lowest and had the lowest spin. the M5 had similar ball speed and back spin and launch as my TS2 but I found the face to be more forgiving in terms of mishits. All are very good drivers. My next driver to demo is the PXG Gen2. The Cobra F9 and the M5 definitely deserve further testing with different shafts. I currently use a Tour AD VR 6 and its tough to find a similar shaft for testing.
Epic Flash SZ 9* w/ Pro Orange 70TX
Epic Flash SZ 15* w/ AD TP 8X
G400 19* w/ AD DI 95X
Apex Pro '19 4-P w/ C Taper S+
SM7 Raw 50/54/58 w/ TI S400
I hit all 3 outdoors on flightscope- Epic Flash SZ, TS3, and M5. For me Epic flash was +2-3mph faster ball speed than M5 and TS3. M5 and TS3 were better than my old x2hot though, ~+1-2MPH faster ball speed. TS3 had best feel for me. I'm not a fan of the dull/muted/thud callaway/TM offerings have had over past couple years.
I own an Epic from 2 years ago and hate it. Despite my inability to hit the old Epic, I'm going with Epic Flash SZ.
Altho, I'm tempted to hold off until i can hit Cobra/Ping offerings.
