Cobra says its Hotter 9 Points technology is better than ever in its King Cobra S9-1 drivers, with the result being improved clubface efficiency, so better performance from off-centre strikes. The clubs also benefit from internal frequency tuning, with the intention of giving golfers a ‘satisfying combination of sound and power'. Ian Poulter plays the S9-1F on Tour, while Geoff Ogilvy and Camilo Villegas play the S9-1 Pro.
