This is not a cutting edge ice tools but they are extremely good for allot of very different conditions. I use them for water ice, Mixed routes in the Alps, Patagonia and in Himalaya. I bring them on everything I get on. I have never tried them on modern bolted dry tooling routes and I'm sure you can find better tools for that, but if you only want to buy one set of tools I would recommend the Matrix.
The aluminum version are good for more brutal handling. The only improvement is the rubber grip up at the top of the axe that is not lasting that long.
