Custom options are one of the biggest reasons golfers look at Sub 70, but custom does not automatically mean correct. In fact, extra options can make a purchase worse if the golfer is guessing. Shaft, lie, loft, length and grip all interact, and a sensible spec starts with understanding which variables matter most for your game.
If you are buying Sub 70 from the UK, this part of the decision may matter even more than the clubhead itself. Get the build right and the range becomes far more attractive. Get it wrong and even a good head can feel disappointing.
Before switching irons, many golfers benefit from checking their current shafts, lie angles and grip setup. Small adjustments can transform ball flight and consistency.

Why Spec Choices Matter More Than the Headline Model
Golfers often spend most of their research time on model names, then rush through the order sheet. That is backwards. The head matters, but the build spec determines whether the club delivers launch, weight feel, timing and strike quality in a way that suits you.
A 699 Pro v3 or 659 CB, for example, can feel very different depending on shaft profile and build length. The same is true across wedges, hybrids and woods. That is why good fitters work from player delivery and preference first, then choose the head and final specification together.
Start With Shaft Weight, Profile and Feel
The shaft is often the most misunderstood part of a custom order. Golfers sometimes choose by brand familiarity or flex label alone, but the more useful questions are about weight, bend profile and feel. Do you swing better when the club feels lighter and quicker, or do you control the face better with more weight? Do you need help launching the ball, or are you already producing enough height?
The goal is not to chase the fanciest shaft. It is to match the shaft to how you load the club and what ball flight you are trying to create. If you are unsure, start by checking what already works in your current set. Your best clue is usually not internet opinion. It is the club you hit most repeatably now.
Related pages such as Golf Fitting Nottingham and Contact Fittings are useful because they frame the discussion around data and feel together, not in isolation.

Length, Lie and Loft Are Performance Settings
Length, lie and loft are not minor details. They can affect strike location, direction, gap spacing and how comfortable the club feels at address. Golfers who stand a little taller at impact or return the handle differently can need meaningful lie adjustments even if the head choice itself is correct.
Loft matters for more than distance. It influences launch windows, spin and how the set works from club to club. That is especially important when ordering irons and wedges together, or when adding utilities and hybrids that may change your gapping. If the build does not fit the rest of the bag, the club can look excellent on paper while creating awkward distance overlaps.
This is why maintenance and follow-up services matter too. Pages like Golf Services Nottingham and Golf Club Repairs remind golfers that loft and lie are ongoing performance variables, not one-off settings you never revisit.
Grip Choice and Overall Club Feel
Grip size is often ignored until the final click of the checkout process, but it changes how the club sits in your hands and how you release it. Golfers with larger hands may prefer more built-up grips. Others want a thinner feel to help face awareness. The right answer depends on comfort, control and how the club behaves through impact.
Swing weight and total weight also matter, even if you do not use those exact terms. Some golfers love a club that feels substantial and stable. Others perform better with a build that feels easier to move. That overall weight picture is why spec decisions should be treated as a system rather than as separate little boxes on an order form.

Use Current Club Data Before You Order
One of the best ways to simplify a custom order is to use your current clubs as a reference point. Which club in your bag feels easiest to time? Which one launches best? Which one creates the tightest pattern? Those answers give you a useful baseline for weight, length and general design preference.
Launch monitor data can sharpen that baseline even further. If you know your carry gaps, spin tendencies and miss pattern, you can make much better spec choices. Our guide to golf launch monitors explained is helpful here because it shows which numbers are worth paying attention to when narrowing equipment decisions.
Common Mistakes to Avoid
- Choosing a shaft only by flex label
- Ordering a demanding head without checking strike quality
- Ignoring how the new build fits the rest of the bag
- Treating grip size as an afterthought
- Assuming a custom option is better simply because it is available
The best custom Sub 70 order is the one that removes uncertainty, not the one that adds more variables. Keep the process grounded in performance needs, known preferences and evidence from your current game.

Conclusion
Sub 70 custom options are a strength when they are used with purpose. Start with shaft weight and feel, confirm length, lie and loft, then make sure the whole build works with the rest of your bag. Do that, and the ordering process becomes far more sensible and far less risky.
