Bill,
Sorry to hear about you accdent but I am glad there were no serious injuries.
Information about wake turbulence is published in the Aeronautical
Information Manual and also a variety of Advisory Circulars. A faster takeof speed would
have done nothing to prevent this accident-- unless, of course it put you
beyond the vortices. The rolling moment imparted by wake turbulence is more than
most light GA aircraft can counter at any airspeed. Best to wait the
recommended time period.  

BTW--Flying a faster takeoff speed or Vr speed puts additional loads on the
nose gear as you must hold additional "nose down" elevator in order to keep the
nose on deck.
