Evan, a ball park formula is:

Takeoff with Flaps 15 degrees, use the last two didgits of the GW, divide by
two, add 2, then add 14.
  i.e.   160,000 is  60 divided by 2= 30
add 100 =          130 plus 2=132= V1,VR
                           132 plus 14= 146= V2

Landing Bug Speed= last two didgits of GW
divide by2, plus 8=bug speed.
i.e. 120,000 is  20 divided by 2= 110+8=128

again these are ball park figures which
will get you within a knot or two of the actual speed.
cheers, Ernie
