In reply to Tom Ripley Mountain Guide:
Just my two pence worth
Started with original dmm flys many years ago, thought they were great then I tried vipers. The newer bronze version and I found they made everything much easier, I wasn't able to climb harder grades with them any more than the flys, they just made it easier.
Last year bought some nomics (they were a bargin)
Not climbed on them a great deal, nice axes, i think I'm just more used to the vipers
Personally at the moment in hindsight I should of just stayed with the vipers, in fact I still have them and still climb with them. Up to you if you have the cash to splash go ahead, I personlly haven't noticed a huge improvement in my climbing with the nomics
