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.

Topspin Plus 16 mains / Synthetic Gut 17 crosses

Prince Topspin Plus 16 (Nylon) in the mains, Volkl Synthetic Gut 17 (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 Topspin Plus 16 alone This hybrid Synthetic Gut 17 alone
Stiffness lower = softer, kinder on the arm 166 163 159
Tension loss lower = stays where you strung it 21 21 22
Energy return higher = livelier, more free power 93 93 92
Spin potential higher = more spin off the string bed 5.3 5.3 5.2
Ball bite higher = grabs the ball harder 0.512 0.500 0.430
String friction lower = strings slide and snap back 0.097 0.093 0.082

What the crosses change

Against a full bed of Topspin Plus 16. Moves are in percentile points, and "better" always means more of the good thing whichever way the raw number points.

  • String friction +5 pts 0.097 → 0.093 COF mains weighted 75%
  • Ball bite −5 pts 0.512 → 0.500 COF mains weighted 85%
  • Energy return −4 pts 93 → 93 % mains weighted 60%

The other way round

Synthetic Gut 17 in the mains and Topspin Plus 16 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 →
