Full disclosure: I'm a total petzl-tool fanboy. I've climbed in the Ergo's, Quark's, and Nomics, and I love them all. I currently own a pair of Nomics and Quarks, and I probably put just about equal time on both sets of tools. I can't quite decide which tool I like better , but I think the Nomic is an incredible tool.
For the first time ice-tool buyer, it's important to keep in mind that most of what you'll hear from reviewers (like myself) is a combination of experience, hype, and preference. I climb with a guy who swears by his BD Vipers, but you honestly could not pay me enough to climb in them--clunky, annoying, and non-ergonomic..the petzl tools, especially with the head weights attached, are the absolute best tool in my mind for my swing style, personal preference, and climbing areas.
If you, like me, prefer a tool that is precise over heavy-handed, ergonomic over straight-shafted, keep reading. The Nomic is a great all around tool, but I find myself reaching for my Quark's on easier ice and alpine jaunts, and my Nomic's on harder ice. The tool has a great balance and flick to it, and with a little bit of detuning, the Ice picks stick super well, and clean easily too. I wish that the handle in the hole was a little lower so as to provide a clip-in point (either at anchors or for umbilicals), but I have found that I can extend that hole down a bit with a small loop of 9/16's webbing. I also like to wrap the shaft with 3M Waterproof Electrician's tape, to allow for effortless matching and choking. You'll never be plunging with these tools, so no reason to leave that shaft naked.
The ergo handle puts your wrist in a much more neutral position for steep climbing, leading to less fatigue and easier swinging--I like it a lot, but I don't care for the swing of the Nomic on easier ice--as previously mentioned, I tend to reach for my Quarks first in situations where I anticipate rampy ice.
Overall, this is a great tool! 4.5 stars!
