Yes, that works but you are still expending a fair amount of effort in stabilizing the pump head and/or grinding the pump into your hand. I know all the tricks and can get the pressure of a tire up to over 100 psi with a Zefal frame pump. But after using the Topeak Morphs, I just don't see the point of all those tricks. I just put the Morph on the ground, attach the hose to the tire, and put all my effort into pumping rather than half into holding the pump and half into getting air into the tire.
