IRL Stats - Vcore 100 (2026), Ezone 100 (2020), Pure Strike 100 16x20 (2024), Speed MP (2024)
For those who, like me, are very curious about stats. I've measured the swingweight with a 240fps camera so it is decently accurate.
The bands here are Babolat silicone bands that go at the top of the overgrip. They weigh about 2g or slightly under. Overgrip is about 5g. Overall, 16x19 1.25 strings + overgrip add about 24g.
I have not measured the Flexibility and have simply used the stats provided by TennisWarehouse.
Yonex Ezone 100 16x19 2020
- Weight: 326g (strings + overgrip + band), 324g without band
- Swingweight: 324sw (s+o+b)
- Balance: 32.8cm
- Flexibility: 69 RA (stiff)
- Depolarized (newer Ezones seem much more depolarized)
Yonex Vcore 100 16x19 2026
- Weight: 324g (strings + overgrip), exactly 300g factory weight
- Swingweight: 326sw (s+o)
- Balance: 32.8cm
- Flexibility: 65 RA (medium-stiff)
- Polarized
Head Speed MP 100 16x19 2024
- Weight: 327g (s+o+b)
- Swingweight: 331sw (s+o+b)
- Balance: 32.9cm
- Flexibility: 60 RA (medium)
- Well Polarized
Babolat Pure Strike 100 16x20 2024
- Weight: 328g (s+o+b)
- Swingweight: 324sw (s+o+b)
- Balance: 32.1cm
- Flexibility: 61 RA (medium)
- Well Depolarized
The Speed MP is quite heavier than the TW ones (they had it at 315g strung. Mine is about 320g. The swingweight seems to match, though).
The Pure Strike 16x20 is slightly lighter, but has a higher swingweight. That might just be because of the overgrip and band - since this racquet has a lower balance and is well depolarized, those may affect the SW more vs how little they affect the Speed MP or Vcore.
I have weighed the Vcore as it came from the factory (exactly 300g), but have not measured its swingweight at that point. My assumption is it would match the 325sw from TW without the overgrip, which means it is adding only about 1sw to polarized racquets like the Vcore and the Speed MP.
In terms of string pattern it seems to go: Speed MP (most open) > Vcore 100 > Ezone 100 > Pure Strike 16x20 (least open)
