From Keiti Tätte:

Why the Sapphire? I just love to throw it! Sapphire is the disc that can surprise you with how easily and far it flies! For me it's perfect for backhand tunnel shots, because it goes straight from hyzer with minimum fade. It is also my main disc for forehand shots. I am a backhand dominant player, but Sapphire makes it easy to gain distance with forehand too!

Are distance drivers only for the pros? Nope. Say hello to our first distance driver in the Easy-to-Use Line. It's light, it's fast, yet still easy to grip and control. The Sapphire is designed to be the perfect partner to the Diamond, our most popular Easy-to-Use fairway driver. With the Sapphire you will get that extra speed and stability in your disc arsenal. It has a slim profile for smooth releases, and it is easy to get a good grip, especially for those of you with smaller hands.
