This is a high-performance string that has gone unnoticed for a while and I don’t know why!

Pro Stock Limited Reserve is a string we purchased because it has interesting characteristics that appealed to us however the client base is small.  Recently, however, with the number of players that are moving away from a polyester string, this has become a popular alternative!

Pro Stock Limited Reserve

In a word, this plot looks very much like that of natural gut, and whatever you think natural gut is still considered the best performance material for racquet string!

What are we seeing here:

• Linearity, the more linear the string the more consistent (predictable)
• Elongation, at 33.1 mm at 50 pounds
• Elasticity, 71.9 %
  • This is the area where the advantages of pre-stretching will be seen.
  • The curve will become essentially one line meaning the string returns to a nominal length after stretching.
• Ultimate Tensile Strength, 163.6 pounds to fail (high), @107.2 mm deflection
• Knot strength, @102.4 pounds, and surpasses natural gut in this property.

What we can’t see in the plot is the construction of this multifilament string.  Each strand is a thin, flat ribbon of polyolefin material.  The ribbons are much like the natural gut.

The plot below is a comparison of natural gut string and is included as a visual to compare to Pro Stock Limited Reserve and show how much natural gut fibers are the same for any string manufacturer.  Of course, manufacturing techniques, bonding agents, and coatings make the difference between a good gut and a not-so-good gut!

If you compare the Pro Stock Limited Reserve to natural gut you can quickly see why it may be a good string to try!
