MSV Co Ultra


On court

The strength of the Co Ultra 1.30 is undoubtedly the access to the rotations.
The spin potential is very high and facilitated by an excellent snapback.
The shape of the strings ensures a good grip on the ball.
Excellent resilience peak and ball weight as long as you hit with decision.

Very good control that ensures precision in the shots even on the plates strings “generous” or not “dense”.
Tests on Pure Aero pulled to 22 kg have responded very well.

The Co Ultra is a competitive mono.
The comfort is not very high even if the static stiffness measured by the team of Stringingpedia is around 0.9 kg/mm that classifies them as medium stiff string.

To be reviewed in terms of tension holding.
The Co Ultra are very performing for the first 4 hours of play (on profiled and aggressive frames like the Pre Aero maybe even an hour less).
After this threshold the string degrades quickly and needs to be replaced.
Excellent for tournaments and where you need a string immediately ready and with high performance.


Below are illustrated the attitudes of the Co Ultra obtained from the measurements of Stringingpedia.In the stringing phase the Co Ultra tend to twist but they have not given me big problems.
