There are discs for all situations. Drivers, putters, and mid-range discs are available in various plastic grades....the higher the grade, the greater the durability. These discs are also classified according to stability. For instance....for a right handed player who throws the disc backhand (RHBH).....an overstable disc will fade to the left. An understable disc is designed to turn to the right. A neutral disc is designed to fly with minimal turn or fade....it should fly relatively straight. To complicate matters....you will often hear a player refer to a disc as "stable" . This means different things to different people. To some(including the disc golf glossaries I have seen) it means neutral. Others will insist it means overstable. As a disc is used more (beat in) it becomes more understable..... this process happens more quickly with cheaper plastic grades.
FOR NEW PLAYERS(ASSUMING RHBH) THE DISC OFTEN TENDS TO FLY "HARD LEFT" UPON RELEASE.
Therefore, overstable discs are not often recommended for new players. Understabe discs actually tend to fly straighter for the new player who has not yet developed power.....wheras an understable disc would "turn".. (go right) for a player with power. As the new players throwing power increases, more overstable discs can be used when needed.. Experienced players will often use overstable discs because of their predictable flight patterns. When thrown with optimal power,even these discs can sometimes be made to turn...then fade later....resulting in a long "s-shaped" flight pattern.These discs also perform better in headwinds. .....which is discussed in another section.
Bottom line: The new player can start with just a few discs...or even just one. Some quality "starter packs" are available that have a putter,mid-range disc,and driver, in a suitable stability for newer players. If you prefer to start with just one disc....here are some decent choices:
Innova: Mako 3(mid-range)
Discraft: BuzzSS or Buzz(mid-ranges)
MVP:Axis or Tanget(mid-ranges)
Lttitude 64: Pure(technically a putter,but used as a multi-purpose disc by many)
If you want to try a driver.....The Innova "Leopard" or Lattitude 64 "River" are solid choices as good first drivers. As you can imagine,opinions will vary on which discs are best for new players.....but most will generally agree to not start with discs that are heavily "overstable".
Big box sporting goods stores often carry discs(often only Innova brand). Other brands can be found at retailers(including online) that specialize in disc golf...."Play It Again Sports" often has an extensive section of both used and new discs. Many discs are available on Amazon. ( Search function at bottom of homepage ).
