Hybrid builder

Two strings,one string bed.

The mains carry most of the load, take most of the deflection and are the only strings that snap back. A hybrid is not the average of its two strings, and which one you put in the mains changes the answer more than which two you picked. Pick both and see where the bed lands.

Estimated, not measured. No hybrid combination has been tested as a bed. These figures are the two strings' own lab measurements weighted by how much of the bed each one actually is. Treat them as a guide to which way a pairing moves, never as lab data.

1 Your mains (the vertical strings)

These do most of the work. Usually the stiffer, more durable string, a polyester for most people who hybrid.

2 Your crosses (the horizontal strings)

These soften the bed and let the mains move. Usually gut or a multifilament.

Nanosilver 17 mains / X-Natural 16 (1.30) crosses

Gosen Nanosilver 17 (Nylon) in the mains, Solinco X-Natural 16 (1.30) (Nylon) in the crosses. Every figure below is estimated from the two strings' own lab measurements.

The bed against its own two halves

A hybrid is only worth the extra work if it lands somewhere neither string reaches on its own. This is where you find out whether yours does.

Measurement Nanosilver 17 alone This hybrid X-Natural 16 (1.30) alone
Stiffness lower = softer, kinder on the arm 157 152 145
Tension loss lower = stays where you strung it 22 22 22
Energy return higher = livelier, more free power 95 95 94
Spin potential higher = more spin off the string bed 4.5 4.5 4.4
Ball bite higher = grabs the ball harder 0.398 0.410 0.479
String friction lower = strings slide and snap back 0.088 0.093 0.108

What the crosses change

Against a full bed of Nanosilver 17. Moves are in percentile points, and "better" always means more of the good thing whichever way the raw number points.

  • String friction −11 pts 0.088 → 0.093 COF mains weighted 75%
  • Ball bite +8 pts 0.398 → 0.410 COF mains weighted 85%
  • Stiffness +5 pts 157 → 152 lb/in mains weighted 60%

The other way round

X-Natural 16 (1.30) in the mains and Nanosilver 17 in the crosses is a different bed, not the same one described differently. Worth a look before you commit.

How this is worked out

Each measurement is a weighted average of the two strings, with the mains carrying the larger share. The share is not the same for every metric: bed stiffness is close to 60/40 because the crosses genuinely soften the bed, but spin is nearer 80/20 because snapback is a mains phenomenon and the crosses barely participate in it.

These splits are the conventional stringer figures, not measurements. Nobody has put a hybrid bed on the machine and published the result, so this cannot be validated against anything. Treat it as a guide to which direction a pairing moves, and never as lab data. The full methodology →
