I've never thrown an actually straight flying fairway driver.
I naturally throw with a very slight hyzer (am working on correcting it) and the SDR went straight and faded very slightly.
Threw at anhyzer and it held it for a while and faded back to center.

One of the best 8ish speeds I've thrown.

I bought this for my wife. She doesn't have a lot of arm speed and doesn't like the way most discs curve at the end. She is getting used to the SDR and is starting to fall in love.

This immediately went in the bag as a go to driver! Any angle you put it holds and excellent for tunnel shots! Highly recommend!

I have heard so many people in the past say "Here try this disc it's very straight." but up till now only a very few have actually done that and, this disc has the exact flight I wish those ones did.

If you're looking for a fairway that will hold a line with a modest fade and low glide this is the disc for you.
