CLUB HEAD SPEED
Those of you who are fond of getting as much distance out of every wood and
iron shot are probably aware that there are three main properties of a golf
club that determine how far the ball will travel:
Club-head mass
Speed of that mass at impact
Flex of the striking surface (and coefficient of restitution)
Clubhead speed is pretty much what it sounds like. It's a measure of how fas

2. It is - If Everything Else (grip/clubhead) kept the the same, switching to lighter shaft will generate more clubhead speed.
I don't have a number to back it up, but to me the cavity-style r7 CGB Max irons have significantly larger clubhead, which translates to heavier, when comparing to muscleback-style AP2.
So the total weight of CGB might not be any lighter (if not heavier) than AP2.

usually, aldila nv is for players with faster clubhead speed, while aldila

prolaunch also has 2 version, blue and red, blue for higher trajectory and
red for lower.
It all depends on your clubhead speed. for beginners, I recommend nvs and

the forward motion allow the hands to get to the ball before the clubhead,
and moves the bottom of the swing arc toward the target so the clubhead
contact the ball before the ground. if there is no forward motion, either I
hit fat or thin.
However, I can not figure out how to combine the move forward motion with
the hip rotation. |

发帖数: 19471 | 9 Hi ET, here's some of my comments in English:
1. The shafts are "uniflex", which means they are between R and S. But I feel
they are more "R" than "S". Maybe because I've been hitting a low
handicappers' iron set before and those are very stiff.
2. The soles are very thick. The advantage is it's very easy to carry the ball
into the air with these irons. You dont have to worry about digging into the
ground (matt) when hitting fat - the thick sole will keep the clubhead
"floating" on the ground. T |

last time the speed recorded was only 89mph, at that time i was such a

A growing number of tour players are choosing to fade the ball with their

with, you need to think again. Tour players don't fade the ball the way
amateurs do. They actually make a draw-type swing, with the clubhead

they do to produce the fade is aim left and make sure the face is open

More golfers initiate the downswing incorrectly than commit any other single

move forward, the wrists uncock and both clubhead speed and square delivery
are inhibited. The key thought of pulling down on the club with the last two

i was talking about ball speed 150mph, not club head speed (even long

using some kind of formula... also LM accuracy at local store is questionable i guess.
if you club head speed 115-120, you can drive 290- 300 yard on regular basis. that's in the range of PRO long hitter level.

also at impact, your shoulder line is a a bit past your toe line. so you

发帖数: 412 | 46 Yes, they should be only used to hold the club in the right plane and
position. All the torque, power and speed come from your body and hip
rotation. Use your big muscle in the back and hip to swing, not the arms and
hands.
Naturally, people intend to swing with their hands and arms. It takes lot's
of hard practice and correctness to learn to use the body to rotate. I am
also working on my swing to limit the arms and hands movement, especially
the early clubhead release during the impact. |
