FLX or Crystal FLX Buzzz--my go-to second shot or approach disc (when too long for an upshot putter).
Wraith--I am partial to Pro Wraiths, but I sometimes use a star or rarely a champion. I use this as an overstable, and long fairway second shot in many ways. I carry a couple seasoned of these when I have room in the bag.
Reaper--It is my most used FH disc and it is often my get out of trouble disc.
If the above are the "A" team, then the following are the "B" team that are usually in the bag (depending on the course) in the following order of importance: Drone, Sidewinder, Beast, Destroyer, Striker. The last five are almost always in my small bag. They cover all the shots I really need with the first three discs. After that it depends more on my likes at the time and the course. I change things all the time, but 90% of the time these eight are in the bag. I have multiple backups of the above.
I change putters alot but for primary putting I usually go back to my Star Aviar P&A that I have had for three years.
