I think you would probably be in your best interest to get 4 or 5 Leopards and learn to throw them on nice flat, smooth lines.
Personally, I think the Leopard is the greatest disc ever created, just because it is so versatile. With the right amount of hyzer/anhyzer, it will do whatever you want and hold a line. Plus you can rip them for a mile.
They are sensitive to OAT (Off-Axis-Torque or Yanking It) which is why I think it would be in your best interest to learn from them. Once you have it dialed in to where you are throwing it 300+ on nice smooth, flat lines then you know your form is coming around and you're ready to start moving up.
