It arrives assembled with your choice of adapter and grip, ready to attach to your driver or fairway wood head.

Who It's For
Good fit if you...
- Want a mid flight with a little less spin
- Swing your driver about 90 to 105 mph
- Play stiff flex
- Want a 67 or 78 g shaft
Not the right fit if you...
- Need R, A or X flex: we build this one in S only
- Need help getting the ball up: the M40X Red is rated mid-high launch
How It Plays
UST rates the 6 and 7 series of the TSPX Blue mid launch and describes it as a mid ball flight with mid-low spin.
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.
The 6 S weighs 67 g with 4.0 torque. The 7 S weighs 78 g with 3.0 torque.

Questions & Answers
Have a Question?
-
How do I choose between the blue, white, and red Lin-Q?
-
How does the UST Lin-q M40X blue shaft compare to the Proforce V2? I've played the V2 for years, and very consistent. Tempted to SEE if the Lin-q would be an upgrade, or just different..... Quite a bit higher in cost for the Lin-q
Hi Todd,
That's a fantastic question, and it's smart to compare shafts, especially when you've found such consistency with the Proforce V2! You're right, the UST Mamiya Lin-Q M40X Blue comes in at a higher price point, so it's worth understanding the potential differences.
Here's a comparison to help you decide if the Lin-Q M40X Blue might be an "upgrade" or just a "different" feel/performance for your TaylorMade Qi10:
UST Mamiya Proforce V2 (Your Current Shaft):
Launch/Spin: Generally designed for a mid-launch and low-to-mid spin with a penetrating ball flight.
It's known for its stability due to a stiff tip section. Feel: Often described as a firmer, more বোর্ডy feel, offering excellent control for aggressive swings.
Kick Point: Typically a mid-kick point.
Technology: Relies on its proven design for stability and energy transfer.
UST Mamiya Lin-Q M40X Blue:
Launch/Spin: Designed for a mid-launch and low spin. This is quite similar to the V2's stated launch/spin profile.
Feel: This is where you'll likely notice a significant difference. The Lin-Q M40X Blue incorporates revolutionary M40X carbon fiber material, especially in the tip section, along with proprietary nano-technology.
This aims to provide increased strength and significantly improved lateral stability while also delivering a phenomenal, smoother feel and eliminating the "boardy" sensation often associated with stiffer-tipped shafts. Kick Point: Generally categorized as having a mid-kick point, similar to the V2.
Technology: The M40X material is a key differentiator, offering a 30% improvement in tensile strength over conventional carbon fiber, leading to more efficient energy transfer and stability.
It's built with more advanced materials and manufacturing processes. Torque: Depending on the specific flex and weight, the Lin-Q M40X Blue can have a slightly higher torque value (e.g., around 4.8° for a 6F4 Stiff) compared to some V2 models (which can be around 3.0° to 3.9°). Higher torque can sometimes translate to more "feel" for the golfer.
Upgrade vs. Different:
Given your description of the V2 as "very consistent," the Lin-Q M40X Blue would likely be an upgrade in terms of feel and stability due to the advanced materials and construction. The target launch and spin profiles are quite similar (mid-launch, low spin).
If you love the V2's consistency but want a slightly smoother, more refined feel, or even more stability at impact (especially if you have a shallower swing or tend to get steep), the Lin-Q M40X Blue could be an excellent upgrade.
If you're perfectly happy with the V2's feel and performance and aren't seeking any changes, then the Lin-Q M40X Blue might simply be a "different" shaft without a noticeable performance upgrade that justifies the cost for your specific swing.
Ultimately, the best way to "SEE if it's an upgrade" is through trying it out, ideally with a launch monitor to compare your numbers (launch, spin, ball speed) to your current V2.
We hope this comparison helps you make an informed decision!
