Don't be scared. Watts are watts. You can ride a bike with a parachute on your back and work just as hard as in aero tucked position. Going a couple mph slower vs faster isn't going to be so boredom inducing that the would be cyclist decides to quit the sport. In fact, it's been said that heavier bikes provide more exercise than lighter bikes.
