After that, someone was done with the computer with those shot analysis, he
told me I can give a try.
I never test my swing speed and ball speed for my driver before. I was
thinking, let's try it.
afterward, I use iphone to take a picture of those analysis.
I circled it with red. 9 shots, 1 of them i pulled, i scratched it.
Hope you can see the other 8. Can someone help me to interpret those numbers

better use stiff to x-stiff; current best launch angle around 10 degree,
better use loft at 8.5 or 9.5 degree add slight ascending at impact, maybe
increase launch angle to 12 to 14 degree will increase carry or total

The ball speed/club speed is consistent. You have a good stable impact point
on the club face.
The launch angle is too low and back spin is high which is due to you swing
is too steep. tee the ball higher and forward shall give you a higher lunch
angle and lower back spin.
you fade to right side may also due to ball position. Again, move ball
forward may help.

But, according to others, high back spin is good to play against wind.
I deliberately de-loft my drive to control the ball flight, that is why I
want the low launch angle.
For now, I wouldn't change my drive set up. But your observation reminds me
that I need tee ball high when I need distance.
Btw, my drive should be draw, rarely fade. If I read the analysis right, the

发帖数: 3067 | 25 be honest, i have no idea about back spin.
that is why i posted that sheet for folks who have done fitting can give
some suggestions.
according to armix, :), it seems more back spin (2000-3000) is good
why low draw hurt your distance? I know low ball flight would hurt you in
carry, but from my number, or my usual play, it works out better especially
tougher courses.

发帖数: 398 | 26 say a little more about the back spin. The higher the back-spin number, the
more ball flight stability, but shorter the carry. Low back spin ball will
fly longer but easy to get affect by the side wind,so usually pros will
control the back spin(mostly launch angle) and side spin (draw or fade)
according to the weather(side wind) and course condition. For driver normal
number is between 2000-3000, iron around 4000-5000, wedge around 6000-8000.
In general ,the more you need shot accuracy, the more you want back spin. | v*****r

发帖数: 4031 | 32 Talking about club fitting, I've gone through the same experience. I was
told stiff shaft fits me best, but I am currently comfortable with regular
flex. I can possibly hit 145 yds with my PW, while that is not the distance
I do with PW in my game, According to the data the system puts together, I
would be supposed to do better in the game, at least driving the ball longer
and getting more GIR.
Anyway, I only use the data as reference to see if there are any swing or
ball striking discrepencies between now and then.

我上次实验adams speedline 打出 3个 300 吗， 到了range结果差得多。
swing speed 慢， back spin 多一点可以多carry. 但是落地少滚。如果fairway 容易
滚， back spin 或大伙小， 距离差不多。
swing speed fast, back spin 小好。

发帖数: 382 | 55 here is my comments.
The ball speed/club speed is consistent. You have a good stable impact point
on the club face.
The launch angle is too low and back spin is high which is due to you swing
is too steep. tee the ball higher and forward shall give you a higher lunch
angle and lower back spin.
you fade to right side may also due to ball position. Again, move ball
forward may help.
Go test the new setup and please update us about the change.:) | A*f

发帖数: 3067 | 57 Thx for your comments.
But, according to others, high back spin is good to play against wind.
I deliberately de-loft my drive to control the ball flight, that is why I
want the low launch angle.
For now, I wouldn't change my drive set up. But your observation reminds me
that I need tee ball high when I need distance.
Btw, my drive should be draw, rarely fade. If I read the analysis right, the
offline are to the left as well. I need the low draw, just personal feeling

I am hitting a low draw a lot now. or even hook the ball. I changed my setup

but this swing plane is great for iron plays.

发帖数: 3067 | 59 be honest, i have no idea about back spin.
that is why i posted that sheet for folks who have done fitting can give
some suggestions.
according to armix, :), it seems more back spin (2000-3000) is good
why low draw hurt your distance? I know low ball flight would hurt you in
carry, but from my number, or my usual play, it works out better especially
tougher courses.

发帖数: 398 | 60 say a little more about the back spin. The higher the back-spin number, the
more ball flight stability, but shorter the carry. Low back spin ball will
fly longer but easy to get affect by the side wind,so usually pros will
control the back spin(mostly launch angle) and side spin (draw or fade)
according to the weather(side wind) and course condition. For driver normal
number is between 2000-3000, iron around 4000-5000, wedge around 6000-8000.
In general ,the more you need shot accuracy, the more you want back spin. | | | v*****r

发帖数: 4031 | 66 Talking about club fitting, I've gone through the same experience. I was
told stiff shaft fits me best, but I am currently comfortable with regular
flex. I can possibly hit 145 yds with my PW, while that is not the distance
I do with PW in my game, According to the data the system puts together, I
would be supposed to do better in the game, at least driving the ball longer
and getting more GIR.
Anyway, I only use the data as reference to see if there are any swing or
ball striking discrepencies between now and then.
