QMS is for pure turnovers and long straight shots between 250-330ish feet. It excels at holding its line
The S-Element is for hyzer flips and low ceiling flat shots.
E-Warrior is for stable midrange shots out to 350ft. The warrior excels in the wind. It always finish with some fade. I compare it to a q-sent because I can snap hard and flat. It will fly straight, with a slight track to the right, and then finish left. Once it starts to fade, it usually has reached the end of its flight. It isn't a disc that is overstable for most of its flight. It is basically an Eagle-X in midrange form.
I carry 11x aviars because of the grip and feel in my hand. I have gone through just about every type of BB Aviar. For driving I prefer my aviars to have a slight dome to them(hence why I use the SP2 and DX BB). I generally don't like throwing putters with sunken flight plates. For putting I like a slight recession on top, tacky grip and firm rim. The 11x Aviar gives me all of that. If the Yeti's didn't bounce off chains, I would still be using them. My discs are all about feel. If a disc feels awesome in my hand I generally have more confidence in it. A lot of discs perform similar lines, especially if you have legit technique, but not every disc feels the same.
