Plastic type affects disc cost, durability and grippiness. Inexpensive plastics, such as DX, Base, Prime, and Classic are often the best choice when trying new discs, before committing to spending money on the more expensive plastics. Inexpensive plastics will wear out faster, but are still a good choice for putters as the basket chains will wear down even the most expensive disc. Generally, the more expensive the plastic, the stiffer it is. This stiffness has a greater durability. As a disc wears, mostly from hitting objects like trees, the flight characteristics will start to change. Discs will slowly become less stable the more they are worn. This effectively increases the disc turn. Stiffness of a disc is also affected by temperature. A G-Star disc is very soft and grippy. Easy to hold tight when wet, but it may be too floppy on a hot day. Different plastic types will have subtle differences in stableness (turn). A glow plastic disc, for example, is generally stiffer than a standard plastic, imparting less turn on the disc. As a player, you may carry several discs of the same mold, but in either different plastics or varying degrees of "worn in". So you can have slightly different flight characteristics.
