Brian Highland’s Stringing Note: Since you wrap an overgrip, buy a 4 1/4″ (Grip 2) handle. Wrapping a 0.6mm overgrip brings the final circumference to exactly 4 3/8″, preventing forearm squeeze fatigue.

Frequently Asked Questions

What happens if I play with a tennis racket grip that is too small?

An undersized grip forces you to squeeze the handle tightly to prevent frame twisting on off-center hits. This constant isometric forearm contraction leads directly to chronic wrist fatigue and tennis elbow.

How often should I restring my tennis racket?

Restring as many times per year as you play per week. If you play with polyester strings, cut them out every 15 to 20 hours of hitting, because polyester goes dead long before it breaks.

What string tension should I use if I suffer from tennis elbow?

Switch immediately away from full polyester strings to a premium multifilament or natural gut at 48 to 52 lbs. The lower tension and flexible micro-fiber cores absorb up to 40% more shock than rigid polyester.
