Used by the Juan Martin Delpotro, the Burn FST 99S is one of a few new frames in 2016 to go more aerodynamic. The FST (Fast Speed Technology) features an octagonal frame shape and headlight balance to enable faster swing speeds to enable a faster follow through. Ideal for baseliners, the Burn FST is designed for players looking to make massive groundstrokes whilst the Precision Spin Effect Technology will assist with more spin on your shots. Wilson has developed the X2 Ergo Shaft which offers customisable handle shape for two-handed backhands, see video below. If you really want to take your game to the max, add the Sony Smart Sensor, compatible with this frame, to measure and improve your tennis all round.
