In reply to aldo56: Aye, i've had a play with the Apex, Viper, Nomics and Quarks in Tiso. From reading reviews online I was keen on the Apex then the Viper then the Petzl offerings in that order but it was a different story once i got them in hand.
I wasn't a huge fan of how the Apex and Vipers felt, much more impressed with the Petzl axes. Decided on the Quarks as I felt the Nomics were a bit extreme for the stuff i'm likely to be doing anytime soon.
I can see how the Trigrest could be a weak spot in the design but it also adds a good bit of flexibility which I like.
Any of these are going to be 10 times better than my current axes!
