Diadem Impulse Reel

If you go through strings regularly and want to keep costs down without sacrificing quality, the Diadem Impulse Reel is a seriously smart buy. You get 660 feet of multifilament string — enough to restring somewhere between 16 and 18 rackets — so you can stock up and keep playing without constantly worrying about your string budget.

The Impulse is a multifilament string, which basically means it's made up of lots of tiny fibers bundled together to mimic the feel of natural gut. The result is a string that's genuinely soft and comfortable to play with, offering that classic, lively response that a lot of players absolutely love. Diadem also added an extra layer of polyamide coating on this one, which makes it more durable and helps it pair nicely with stiffer poly strings if you fancy going hybrid.

This string works especially well for players with slower to moderate swing speeds who want some help generating power without having to muscle every shot. It's also a go-to option if you've ever struggled with tennis elbow or general arm discomfort — the softer feel takes a lot of the shock out of each impact, which makes a real difference over a long session.

The Diadem Impulse Reel comes in 16 gauge (1.32mm) and 17 gauge (1.25mm), so you've got a bit of flexibility depending on how much durability versus feel you prefer. Natural colour, clean look, and a string that genuinely delivers where it matters.
