Dynamic Discs says:

Designed with the newer player in mind, the Underworld will allow any player to accomplish an anhyzer shot. It is under stable and low profile. Great for players to buy as their first disc, the Underworld will be just what a beginner needs. For professional players it makes a great continuous anhyzer line and is great for rolling right out of the box.


About Tournament Plastic:
An advanced version of VIP-plastic that contains technical polymers. You cannot see through Tournament plastic. The durability of Tournament plastic is at the same level than VIP Plastic, but the Tournament's grip is slightly better. Our Tournament plastic is closely similar to Latitude Gold plastic.
