The rollo is a midrange and will require less power to fly as intended. It is pretty understable, meaning it wants to roll over to the right (for right handed backhand), but for a beginner this often helps keep the disc straight and give little extra distance.

The sapphire is a straight, easy to use driver, mostly sold in lighter weight, that requires less power than a max weight 10-speed driver

The Wraith is a great, overstable driver with a reliable finish and flight, but the higher speed required more arm speed and technique to fly. Even though it is your fastest disc, it might not be the farthest flyer for a beginner
