While the Oban shaft showed flashes of potential, the video concludes that buying premium shafts blindly on eBay is risky and no substitute for a professional fitting.
Their scorecard
Forgiveness: 4/5 — Surprisingly forgiving for a Triple Diamond
Distance: 4/5 — Consistently in the 270s
Sound & Feel: 5/5 — Premium feel at impact
Looks at Address: 4/5 — Bigger, more playable shape
What they rate
Oban shaft provides a lighter feel and active kick
Triple Diamond Max head is exceptionally stable for a low-spin driver
Potential for higher launch with the Oban setup
What they don’t
Shaft dispersion was inconsistent compared to stock setup
Shaft aesthetics are relatively plain for an 'exotic' product
Difficult to dial in loft/lie without professional data
