In reply to Karus:
Then we agree "seems" and "is" are two totally different things.
High clearence tools like the Nomic make terrible hammers to begin with. Add a bunch of weight on the back end of them and you negate much of their great balance as a technical tool. If you need a big wall hammer to pound pins, carry a third tool. It will be more efficent.
I build a Nomic hammer. Not a head reinforcement. Petzl's hammer is based in part on my design work, which I gave them years ago.
Petzl decided bigger and heavier would work. Makes perfect sense on the more generic design and use of the Quark. The new Quark is certainly a better all around tool than the old Quark. Just because you can bolt the new Quark hammer and adze on the Nomic doesn't mean either make sense. I have no doubt they were looking at improving the Quark not the Nomic with that design effort.
Make the hammer protrude far enough from a Nomic shaft and you will make the hammer more useable. Of course every mm you put the weight farther behind the shaft the more you loose balance and pentration if you can't keep the shaft perfectly aligned in a swing.
Make a choice...decent but not great hammer... or... a great mixed/ice tool that will pound a pin when required.
I have actually used both hammers. Which is why I will continue to build a better hammer for any generation Nomic.
Bjørn-Eivind Årtun used two of the my hammers on his and Colin Haley's new route, Dracula, Mt Foraker, in June 2010.

After their '10 season in Alaska, Årtun asked if I could cut a a pair of 4mm hammers instead of the current 7mm hammers he was using. The idea was to drop even more weight and help get back to the original balance of the Nomic.
Imagine that?
Adding weight to the back of a Noimic is going backwards. If you have to add weight you want it as close to the shaft as possible to retain the balance.
Cold Thistle production hammers weight 34 grams per tool. The Petzl hammer weight is 58 grams. Nomic pick weights are 62 grams. Most will chose to use the C/T hammer and no pick weight on a Nomic. If you climb on the Nomic you'll already know just how easily it is to change the balance of the tool.
