The illustrated disc flight line is based on the manufacturer field testing results, during its development process. So, to level the playing field we chose to put a different spin on things for such visual illustrations. Sticking to the manufacturer's test results will offer you a good baseline for how that particular disc will fly.
The Innova Star Tern is a disc designed for distance, even with lower speed arms. The Tern is an understable distance driver that boasts maximum glide and can be forced over easily. It has a small rim for a distance driver, and it throws well right out of the box.
When you're throwing the Tern whether backhand or sidearm expect it to be understable. The -3 turn on the tern means that for most of the flight it's going to be turning, and then at the end it will run out of power and fade back. This is useful for when you're in the woods and you have to throw around the trees, or in an open field when you want to get 350+ feet of distance as well as end to one side of the fairway. It's a 12 speed disc that's designed to be turned over during flight, that's the natural flight path of the disc. It will be an S curve, but less fade so expect this disc to end more towards how it starts.
Star Plastic is durable and affordable. It's twice the price of DX plastic but it will last you significantly longer and retain the flight characteristics better. The grip is awesome on a Star disc, it's perfect no matter the weather and comes in plenty of different weight and color options for players to choose from.
