If you can afford it, buy a pair of Grivel G14s. I have a pair of G12s and have just got some of the New G14's.
They have much longer technical front points than the g12s and are far superior for steep ice and mixed. They are also well set up for general mountaineering.
I use a pair of Nepal Top extremes and they work very well with them.
They will be easier to climb with and will last a long time and are much better than your g12's.
