1. Augment putters. Two thinkings here: throw the same putter, maybe in different plastics, for all your driving, approach and putting needs. Or a lot of Pros would say to have putting putters be separate from your approach/driving putters. I prefer the later. Suggestions:
- Get at least one more Aviar for putt and approach, and to practice putting.
- Discmania P2, Dynamic Discs Judge/Warden or Axioms Proxy/Envy for drive/approach. If it is solely for driving, get the higher end/more stable plastic. e.g. I drive with a Fluid Warden currently (although I'm gonna play with the proxy).
- Zone for Forehand, best thing for short flicks IMO.
2. You might want a second Mid that is more stable. Buzzz is a great choice. Or you might get used to e.g. an Envy for this type of shot and skip Mids.
3. Speed 7-9. You might want a less stable Fairway/Control driver for hyzer flip, smooth turnover shots, tunnels, etc. Innova choice is Leopard, but I like the Legacy Patriot. Or for more speed, I like the DGA Pipeline.
4. Speed 10+. I'm a big fan of Innova Tern, or Discmania DDx at Speed 12. Less stable than your Destroyer. Tern has a great S shaped glidey flight, DDx does too, but less pronounced turn. At Speed 10, I like the Discmania PD. It would be similar to your Thurderbird, but I find them less overstable. Nice straight lines, holds the angle you put on it well.
What fun to have $200 to spend!
