Do you mean you switched to a Silca chuck?
I've got the Nashbar L'Orange V2 pump, and I like the concept but man is it hard to pull the chuck off! I've gotten into the habit of spitting into the chuck every time I use it so there's a little lubrication in there.
I once ripped a schraeder valve right out of a tire!
