great session Ian but is there any way to get those spin numbers down ????  I have about the same ball speed as u 148-153 avg and i keep my spin under 2000 and my carry numbers and total are a bit longer.  Best i have seen this year is 270 carry and 296 overall at 155 BS 1800 spin

How would this relate to real world conditions?
Depending on your ball speed, but wouldn't sub 2k spin equate to knuckleballs?

No i have found on trackman that even a 1500 backspin will carry forever if you have relatively low sidespin and a good launch angle......If you have a ton of draw spin and a lower launch angle, it will be a screaming knuckleball without much carry....my best hits are at 1600 and above for maximum carry and distance but i have a higher launch angle......my mistake is when i have too much side spin in addition to low backspin......In real world conditions, a 150 ball speed with 1800 spin will carry about 255-260 and roll is dependent on the pitch of the ground and the firmness.  If the ground is hard and u hit a speed slot, roll can be up to 60 yards but if you hit a soft spot or a uphill transition, roll can be as little as 0-5 yards.

I had similar experiences with slowish spin numbers on my fit....
1800-1900 still gave really good carry but lots of Roll out...

I guess you will need to launch high enough to get decent carry numbers with such low spin.

But i also ordered a few new Cobra drivers with various shafts

I love this. Just rock up and splash the cash. Awesome :)

Robbie, have you hit the new Mizuno JPX 900 driver yet?

Yes, i have tried the Mizuno, i actually like the funky colors, that driver just looks horrible in terms of color scheme but i like it......way too many adjustments for me.....i have several friends who swear by that club and they pound the crap out of it......However it does not work for me, there are several clubs that i have seen work for a lot of people and not for me......i think it depends on your ball speed and angle of attack as well as how much of a center hit you can repeat consistently.   The longest driver for a crappy swing with not much swing speed is the Cobra LTD......it reminds me ozone of the earlyl Epon driver ( techinity 460 ) but lower spin by about 1500 and tighten dispersion.

Im not getting any magical distances, I'm just getting my best hits with average swings.....my average carry and average overall distance has increased greatly and it seems all my distances are within 10 yards of each other and all my balls land on the simulator fairway.  However this is indoor golf and I'm not sure how it will perform outdoors.  I know the driver looks like crap but sounds and feels great and travels really well.

I guess you will need to launch high enough to get decent carry numbers with such low spin.

On the Simulator i get launch angles of 15-18* which seems too high for golf compared to other peoples launch......i will have better numbers and trackman outdoor data in a week or so once the ground dries from the storm.  I do know i hit a high ball and last time i was on trackman outdoors with my 2017 M1 460, my launch was 18* and i had spins as low as 1500 carry up to 270 which was verified by trackman and laser. My height was 40-44 yards.  My swing speed is modest and i tend to hit a draw....Whwn i put a draw spin and low spin on the ball, it fails horribly.  A sidespin of - 800 and backspin of 1100 results in a carry of 180 yards and then it is offline by 80 yards.  Basically a screaming knuckle ball which will run into a hazard or OB with zero chance of being playable.

* I am a "older" golfer so my averages vary depending on which old man ailments i wake up with......the Cobra King LTD worked spectacular when i was having my old hurt swing with no legs.....basically stiff and tired and sore so less rotation followed by a sway and then a lunge.  Most drivers will punish me into quitting the game but the King LTD rewarded me like i was Superman.  I feel better today and will be testing again this afternoon.  I don't want to waste too much energy though, I'm playing against King Kong and Iron Byron on Friday.

Tried the Callaway Epic and Epic subzero today. I am currently using Ping G with stock shaft and carry around 210-220 yards with 140 ball speed. Too much spin at 3000-3500. Tried the epic subzero today and carry 241 yards with 2200 spin. Amazing stuff. I never though a high handicapper like me would suit sub zero. But the sub zero is really forgiving.

Hey nob, i didn't believe it at first but yeah.... i would say it is as forgiving as ping g. Mishit and bad shots are due to swing. I was testing on GC2 launch monitor and frequently rotating between the Epic/Epic Sub zero and Ping G. Shaft on Epic and Epic sub zero is stock fujikura pro 63g Regular and ping G is the Alta 55 stiff. Ball speed is 140 and my swing speed is around 96-98. The Epic Sub zero feels slightly more forgiving than the normal Epic as mishit goes equal distance.

I came home did my research and found out the MOI for Ping G is 5400+ whereas the Epic is 8000 and the Epic sub zero is 8500!!! So that made sense. I am going to America Golf and try it on trackman. I need to see the numbers and the ball flight at least on the range to commit to it. Ping G has been short but an ultimate fairway finder for me.

Those MOI numbers are not apple to apple comparison.

I believe those 8000+ numbers are total MOI ( horizontal and vertical combined. )   for the Epic

But the 5400 for the Ping G is the vertical MOI only.

There is a conforming limit of 5900  g cm2 defined by R and A  for the vertical axis MOI.

Moment of Inertia (MOI) Limit:
When the club is in a 60 degree lie angle, the moment of inertia component around the vertical axis through the clubhead's center of gravity must not exceed 5900 g cm2 (32.359 oz in2), plus a
***

It would be interesting to see what the Vertical MOI alone is for the Epic.

I hit this a little higher than I'd like.... hence I went for the SZ.

Feel is stunning, a very Solid BUT soft feeling ... in my mind, you can almost feel the bars behind the face.
Roll on tomorrow when mine arrives
