Who It's For
Good fit if you...
- Launch the ball too high or spin it too much
- Swing about 90 mph or faster
- Want a 66 to 85 g shaft in S or X flex
- Want a firm, stable feel
Not the right fit if you...
- Need help getting the ball up: the Lin-Q PowerCore Red is rated high launch
- Swing under 90 mph or play R or A flex
How It Plays
UST rates the 6, 7 and 8 series of the TSPX Black low launch and describes it as a low-launch, low-spin shaft.
Toray M40X is a high-strength, high-modulus carbon fiber. UST says it adds lateral stability through the swing so more energy reaches the ball at impact.
Weights run from 66 g (6 S) to 85 g (8 X), with torque from 3.6 down to 3.0.
