Pick a stable disc, right in the middle of the chart. If you pick a disc that is more neutral in its stability, and you learn how to throw it flat and hard, this will be the foundation of your game. I would recommend you pick a stable disc and buy two of them. Purchase one max weight (175g) and one in the 165-170g range. Use the lighter disc in open fields and tailwinds. Use the heavier disc in the woods and in headwinds.
If you are new to disc golf, the fairway drivers are a good place to start, such as the Innova T-Bird. A brand-new T-Bird starts out a little overstable but, once the T-Bird gets broken in, it flies dead straight--this disc should be in everyone's bag. For distance drivers, the Innova Wraith is a good choice, but I would recommend the Innova Orc. Although it's not quite as fast as the Wraith, the Orc flies dead straight and tends to be more consistent.
As you improve your game and develop more snap, you'll start turning over that Monarch. That S-Curve you're getting from the Monarch will instead curve right...and curve right...and curve right into the ground. At that point you can keep it in your bag as a roller. The Beast will always be good in a tailwind, but eventually you will begin to overpower it, too. The Starfire is a good all-around disc, but at some point I would recommend investing in premium plastic. After a few tree knocks, that DX plastic won't hold up and the disc's flight characteristics will change dramatically. I feel that DX plastic is fine for mid-ranges and putters, but the drivers travel at such high speeds...you would be better served by investing in premium plastic for your drivers.
