HI
a) rotate normally to avoid a tail strike or an engine pod strike depending
on your aircraft type
b) go to your max allowed pitch attitude..sometimes the limits(e.g 25 deg)
is set for pax comfort
c) check your max ias for the T/O flap settings, if max pitch attitude is
reached and airspeed is still increasing be ready to retract flaps to the
next setting and then all the way up
OR
ask for the aircraft to be loaded with ballast and/or extra fuel to offset all of the above
why not consider a lower T/O flap setting(the lowest) according to your aircraft type
