Should polyester go in the mains or the crosses?

Usually the mains. Main strings dominate spin and durability. Soft crosses add comfort and keep the stringbed from feeling boardy.

Are hybrid strings good for tennis elbow?

Often better than full polyester. A soft cross (or soft mains) reduces shock. Full multifilament or gut is still gentler if your arm is already sore.

Do hybrids cost more?

You buy two sets or reels worth of string for one racquet, so material cost is a bit higher, but many players restring less often than with full soft string.

Mix a stiff main and a soft cross (or the reverse) for spin plus comfort.

Quick answer & tips ▾

A hybrid string job uses two different strings in one racquet: usually a firmer string in the mains and a softer one in the crosses. Polyester mains with a multifilament or natural-gut cross is the most common club setup. You get more spin and durability from the poly, with a softer feel and a bit more power from the cross.

Some players flip it (soft mains, poly crosses) for a plush feel with a little extra control. Start with the middle of your racquet's tension range, and if the poly feels harsh, drop it a couple of pounds relative to the soft string. Hybrids are a smart step when full poly is too stiff and full multifilament breaks or feels too loose.

Key tips

Most players put polyester in the mains and a soft string in the crosses.
String the poly a little lower if your arm feels buzzed.
Replace the job when the poly goes flat, even if nothing has broken.
Change only one variable when you experiment: mains, crosses or tension.
