Hi Piperboy, I think it all depends upon what you want to do...
If you are taking off straight out into a 15 knott wind. Where would you prefer to be in five minutes? Ten miles down-range at 3000ft. Or at 4000ft just above the end of the runway? (using Vy+ or Vx. resp.)
There are so many V speeds, even one for the max speed to open the windows.
