Diadem Impulse perfectly blends comfort, touch, power, and feel.  Players with slow to moderate swing speeds will benefit from the power of Impulse. It is designed with an extra layer of polyamide coating to handle the sharp edges of Solstice for those players looking to a hybrid.  It's also great for all players who love a multifilament's classic gut-like feel. Tennis elbow sufferers looking for a softer, more comfortable string should also try Impulse.
