MSV FOCUS HEX ULTRA is one of the latest releases from the German brand well known for hi-performance
co-polyester strings and multi. The FOCUS HEX ULTRA, with hexagonal shape and available in 1.10-1.15-
1.20-1.25-1.30mm gauges in white and black color is the natural evolution of the "modern classic" MSV
FOCUS HEX.
We tested the 1.25mm 17 gauge string in white version with our pro-t-one string-lab machine for the traction
test and for the hysteresis test and with pro-t-one string-killer to get semi-dynamic stiffness of the poly
extrusion.
The traction test from 5 to 35kg shows a good linear and constant behavior of the polyester extrusion, with
consistency and medium-high static stiffness (average value=0.90-0.95kg/mm).
The dynamic stiffness with used string, measure of comfort and impact perception on the arm during the play
but also spin production, stands at medium-high values with 230g/mm  220lb/inch, typical values for
competitive racing strings dedicated to powerful and racing players looking for a perfect combination of spin
and control with good snappy response.
