What do you mean by "regular manual pump?" Is it a floor pump, a frame pump, or a mini pump? I know I've become very very tired pumping up a tube with a mini pump, ergo, I don't use them any more. While infinitely better than the alternative of carrying nothing, they are just too inefficient to rely on, especially for high-mileage riders. Floor pumps are generally very easy to use but are bulky, and frame pumps are generally a good trade-off between efficiency and portability.
