instructors will tell you that because the thrust is so close to the center that you don't need a lot of rudder to keep the plane upright and straight, this is true if you are comparing the amount of rudder required in the crj to what is required in the 737.. when you think you have put in enough rudder, give it just an inch or two more and its good.

also on the side note if the faa sees you staying on the runway trying to get that extra speed to help you maintain control after a v1 cut they will send you packing. ask the guy who just did his checkride here at pinnacle while the fed was in the sim. staying on the runway after you are supposed to rotate does not guarantee that you will have the climb performance required to clear all obstacles... remember that 35ft crossing thing?? well that is what its about. not a big deal in mem, or detroit with a 10000ft runway, but get into roanoke, or somwhere else with some potential hazards and it can make a difference. it may be a good technique in the sim but a good checkairman wont allow it, and the faa sure as hell wont.
