I have a few favorites, some of which unfortunately do not get thrown much because I do not want to lose them.
Seasoned dyed Star TeeBird. 9 out of 10 times does it not only do what I want it to do, but it does it beyond what I would ever expect out of it. The problem is always that 1 out of 10 times might be the one time I lose it for good. It already has two aces on it, so it gets a well-deserved spot on the wall. I have been trying to season other TeeBirds to act like this one, but so far I have been unsuccessful.
Dyed Second Run Ion. One ace but never a really good putter. I just never could part with it.
Dyed Star San Marino Roc. Almost the same dye as the Ion. It also has one ace on it. It was a fantastic driving mid in the forest and second-to-none when making approaches in the open field. Like the TeeBird, I have yet to find a replacement, whether it being another San Marino beaten in or something else like Ranchos, Ghosts, or Roc3s. Currently I am working with M3s to see if they can get close.
I have two dyed (see a theme) Champion Leopards that are quickly growing on me. The one with the star dye had two practice aces on it on the same hole on the same day. (I define a practice ace as throwing 4 or 5 discs on each hole; in this case I played multiple rounds and aced with the Leopard during the first and third round).
