Get the DGA Rogue in Proline plastic. Proline plastic is a great mix of durability and grip. The Rogue is a maximum distance driver disc that will likely fly straighter for you than many of the new fast drivers on the market. The Rogue is fast but is easily controlled because it doesn't have a massive fade at the end of its flight path.
Disc Golf Association recommends the Rogue for beginners and advanced players alike.
