I was always taught to keep power in until at least 10ft, if not through the touchdown, in a swept wing jet. You guys are absolutely crazy to reduce to idle at 100ft. I guess a couple of slam landings will probably reinforce that view... Not sure if the CRJ is any different than any other jet (I can't see why it would be).. but even on a clean wing jet such as the F100 or DC-9-10/15, you kept the power in until at least 50 ft. On the Mad Dog and 75/76, you WILL go CRASH with a loud noise pulling it to idle at 100ft...
