Familiarity: I've used it once or twice and have initial impressions
Just replaced several year old Pulse. The features, size, ease of use, marketing of Black Diamond will surely make this the new standard. The harness is also very nice. Watch for it on sale, I picked it up for $299' no brainer. General impression is I like it better than the Pulse.
