In reply to wbo:
Haven't had a play with the Singing Rock ones. Simonds axes generally have a nice feel/balance to them but whilst a couple of climbing partners gave used some over the years, I haven't.
Unfortunately I've now been climbing so long that most of the axes I've tried over the years (Vertiges, Pulsars, Aliens, Predators, Tornados, Hurricanes, Takoons, original Hornets, original Anacondas, original Quarks, original Ergos, original Flys, Rebels, Monsters etc.) are no longer in production...
The thing with axes is that different models require a subtly different swing with varying amounts of wrist movement. Some people find it easy to adapt whilst others don't. Especially with the less technical axes this can lead to wildly differing opinions and there is no substitute for getting hands on experience.
