unless you want to settle for low power and long flash durations or a heavy cable and high cost (read: Quadra).
The Quadra A head can reach up to 1/6000 flash duration at 133ws. (No clue if its t1 or t5 but even half that would be pretty darn fast)
Not sure what the fastest speed at full is, but with that option, i dont think i'd ever call the quadra "slow."
I wouldn't call it weak either.
But i'd sure as hell call them pricey, try not to find faults where there aren't Mr. Buff, you wouldn't like someone doing that to your products. The big fault with the quadras is the Price point.
As far as i know, (And i'm sure there are some Profoto/Bronc/etc variants) the most used flash for sports on the high-end is the Ranger A system, which offers a whole LOT of power, and fast flashes, also uses a head/pack combo that can be mounted in the rafters, isn't very big. By high-end, i would mean SI high or just major publications high. I am now curious enough to see if i can find out what SI is using to shoot finals. I remember reading some thorough guides but i don't remember them mentioning what kind of equipment they'd use or be allowed to use (Mindful of the TV cameras i'd guess)
I am sure there are ways to use a flash like an Einstein on the court, mounting stuff to rafters doesn't need the size of a SB-900. You just need to do it properly, and i'm sure the Einstein could haul its weight and with its price point, become a viable option for shooting sports for mid-end photographers.
Don't make me out to be a eli fanboy, i wouldn't think twice about selling them and getting other lights if i could find a good deal. But for the years i've spend with elis so far, i had to learn about them and see if there are viable options in the future.
