I'm a beginner/intermediate and the only driver in my bag at the mo is a discraft tracker, and whilst I can use it fairly well, I have felt more comfortable with the stability of my mates Innnova Valkyrie. I'm tempted to purchase a Valkyrie but thought I would post a topic up here to see if any of you guys had any other preferences.
The Sidewinder seems popular amongst the Croydon guys, it's basically in the same family as the Valk, but a little easier to turn to the right, and will hold straight for longer:
The tracker seems to be the way to go... i went and got a glow one which is nice cause it's really grippy... i've also got a nice bright pink Wraith, which is an unpredictable wench, sometimes it flies like a dream (especially forearm throws) far and fast, other times i spend a long time looking for it in bushes... behind me!
tempted to go for a Sidewinder next or an Avenger. :twisted:
So you can see that the XL and the Tracker are very similar, but if you want a disc that goes more right (assuming you're throwing right handed backhand), you pick something with lower High Speed Stability, say a Sidewinder. If you want something more left turning, you could try a Teebird.
