I use C02 cartridges on my road bike and a Topeak Morph series pump on the touring bike. On tour I really needed a good pump since I was maintaining three bikes including mine for a 4200+ mile tour. That is a lot of pumping and the Topeak was great. Mine was actually a Mountain Morph, but it the same as except a bit shorter that the Road Morph. The Mountain Morph fit better on the frame of my touring bike.
