How do you break the Presta stem off? By pulling or jerking the pump head recklessly to the side while inflating, or by yanking the head off the valve at an angle. They only break when the stem is unscrewed. Occasionally they come out when unscrewing as well.
When using a hand pump, I put my left hand around the pump with the side of my hand against the tire. Then I use my right hand to pump. With my left hand I make sure it stays right against the tire, that way the stem doesn't get any pressure on it. When I push, my hand keeps the pump from moving in that direction. When I pull, I have to more actively keep my hand against the tire, making sure it doesn't get pulled away from the pump.

Pray tell, which "tri-state area" are you talking about? Berkeley isn't a state.
It's a state of mind, my friend. Of mind.
I suspect I break the Presta heads with the pump, yes.
It's a floor pump, and I'm probably not gentle with it.
Oh come on, don't you hate it when people don't give answers. There's quite a few "tri-state" areas.
