Well, on my defender Swift (Fitness pool) + Fly both one-slotted for Flight Speed with +3 SOs didn't hit the flight cap. It took 2 SOs in Fly and 1 in Swift.
"Sprint" (the inherent) still can't be slotted for Flight speed AFAIK.
3 fly SO's in flight + i think its 1 or 2 in swift = cap, tbh ive got 3 in flight and 1 in swift and it feels same as 3 in flight.......
but thats just me 
Sooo.
With the recent changes to fly, and the ability to enhance its speed by using both Sprint and Quickness, can anyone tell me what sort of slotting needs to be done slotting-wise to hit the flight speed cap?
