String type chooser
- Synthetic gut: budget all-rounder; fine for beginners.
- Multifilament: arm-friendlier comfort and power.
- Polyester (poly): control / spin for heavy hitters; harsher if too tight or too dead.
- Hybrid: poly mains + multi crosses (or reverse) to blend control and comfort.
- Natural gut: premium feel — ask your stringer about care and cost.
Retail string sets on Amazon are fine for DIY curiosity; most players are happier handing the frame to a pro machine.
Mobile Racket — tell them your arm history and how often you break strings.
Gut, multi, poly, hybrid — plain English
Natural gut — premium feel and tension maintenance; costly; humidity care. Multifilament — synthetic comfort/power; arm-friendlier. Polyester / co-poly — control and spin for full swings; can be firm on the arm. Hybrid — poly mains + multi/gut crosses (or reverse) to mix spin and comfort.
- Arm issues → start multi or soft hybrid, not stiff poly at high tension.
- Heavy topspin baseliners → shaped poly or poly/multi hybrid.
- Feel players / doubles touch → multi or gut blends.
