I meant to post this earlier, but I figured better late than...
Petzl is discontinuing replacement picks for the original Quark and Ergo ice tools. If you use and like these tools, I still climb with my Ergo's almost all the time, I suggest that you ask around and but whatever ones are still available. I have 3 sets stockpiled and would buy another is possible.
I know that many people will say that there are newer tools that are supposedly better, but that is not the point. The Ergo suits the way I climb better than any tool I have tried, EVER! I don't want to get rid of them. And I am sure that I am not alone.
Word to the wise...
