HighString Hi Storm8

The HighString Hi Storm8 is an octagonal olefin polyester monofilament.

The Hi Storm8 is available in midnight blue and is available in 1.20 mm gauge and in the most competitive 1.25 and 1.30 mm.

The price of a set of 12 meters is about 6 euros while the reel of 200 meters is about 70 euros. The prices indicated are those shown on the TennisLand website.

As previously reported in the Zeus review, the graphics of the packaging of the 12-metre set deserve a special mention. On the back of the package are the results of the pro-t-one and Stringingpedia tests and in particular the recommended tension range, as I consider extremely useful and important to disclose.

On court – The pros

On court the Hi Storm8 is quite balanced with strong aptitude for control and generation of rotations. The feeling of control is very high even at low tensions. The progressive plasticization of the string ensures that the player always has the maximum confidence in the execution of shots, both defensive and offensive. The easiness in generating spin favors the execution of extremely “heavy” and deep shots and allows you to draw insidious trajectories and never trivial … however, always under control.

The power returned is more than good but not free, especially in the 1.25 and 1.30 mm gauges. The Hi Storm8 in fact requires strong movements to be triggered properly and make the most of its characteristics. It is much easier to generate power in the 1.20 mm gauge, indicated for players who are “less competitive” and who do not have problems with frequent breaks.

Very good tension holding (both static and dynamic) that keeps the string playable at high levels for about 14 hours. Definitely an excellent result when compared to the average duration of the segment of monofilament competitions.

The Hi Storm8 is a very stable, little moving monofilament, particularly suitable for “generous” stringbed with “open” strings pattern.

On court – The cons

Being a competitive monofilament, it does not shine for comfort. The Hi Storm8 is in fact a “tough” and rather rigid string, designed for well trained arms that know how to stress it properly. This aspect is mitigated in gauge 1.20, which is “more human” and manageable even by a more amateur or less competitive audience.

Who it is indicated for

The Hi Storm8, in the larger gauges, is recommended for a competitive audience looking for a string with strong control skills. It fits perfectly into the modern game based on powerful strokes and extreme rotations. Perfect when mounted on “lively” frames with generous stringbed and “open” string patterns.

The 1.20mm gauge is a universal string, it loses something in control but gains points in terms of comfort and playability. It adapts to different styles and levels of play, winking at a more amateur audience and with less competitive ambition.

Testing setups

The tests were performed by stringing the HighString Hi Storm8, on:

  • Wilson Blade 104 custom (gauge 1.25
    Wilson Blade 104 custom (gauge 1.25 pulled to 21 kg)
  • Wilson Blade 104 custom (gauge 1.30 pulled to 19 kg)
  • Diadem Nova (gauge 1.25 pulled to 22 kg)
  • Diadem Elevate (gauge 1.20 pulled to 21 kg)
  • Yonex Ezone 98 custom (gauge 1.25 pulled to 20 kg)
  • Yonex Ezone 98 custom (gauge 1.20 pulled to 20 kg)

To conclude

The HighString Hi Storm8 is a monofilament with outstanding control and spin capabilities. The power is there but must be triggered with strong movements. Excellent static and dynamic voltage holding.

More “human” is the version with a smaller calibre (1.20 mm) that adapts to a more amateur audience and with less competitive ambitions.

We thank HighString (in the person of Federico Desi) who provided us with the strings for our tests.
