Story-time: So there I was, high up on a gorgeous gem of the Northeast, Paradigm Shift. Having gained the last ramp of ice to the trees, I took in the Vermont pastorale countryside before taking the final few swings to the top, the first of which gave an odd vibration that took me seconds to process: the pommel of my trusted Petzl Ergo had broken off in my hand, leaving a curved metal shaft, with no handle at all, in the ice. I fired in a few screws, hauled up my friends X-Dreams, finished the climb, and ordered a pair myself that night before returning to the same crag the next day to do the climb again, and a few others, on his X-Dreams, excitedly getting used to what I thought would be my go-to tool for all of my new quests.
As I waited for my new tools to come in, Petzl managed to get me a replacement faster than I could even finish the drive home that day - a clear signal of the winning strategy of community-embedded sales reps - and given my long-term muscle memory and short-term mental memory (a hallmark I took up, understanding it to be a useful combination for winter climbing), I happily continued climbing on Ergos and when they arrived, hung the X-Dreams and associated parts in a remote corner of my closet.
I believe both tools are great, it's just a matter of what you get used to. But if you want a pair that wont snap in half, buy my completely new, never swung X-Dreams. With head weights, two additional ice picks and two additional mix picks. Comes wrapped - I tried this wrap on my egos and didn't like it as much as what I typically do so I can't actually recommend it. Some like it, so up to you to leave it or cut it off.
$550 + shipping via USPS priority, whatever that comes out to be.
