As soon as I saw that Black Diamond had updated their Livewire I new that the best way to test them was to get a set and take them to Sardinia. The new design in my opinion is great. I really like the new functional ergonomic features.
First off is the weight. The new draw has a total weight of 106g from 111g of it's predecessor. When you are carrying 12 of them, that weight difference is substantial. The 12-cm long Vari-width dogbone has been improved from 12cm dynex.

The new hot forged keylock Dynotron biner on top and Livewire on the bottom are very nice to handle. When you’re feeling the pump after to or three hard pitches it is nice to have a smooth keylock biner for easy removal from your harness. Both of the biner’s new design include a tapered edge to help avoid fumbling while in route. The lower biner, Livewire, has ridges added to the spine of the biner. This feature helps add friction while opening the gate to insert your rope. The gate on the Dynotron is tapered as well, for ease in opening. The Livewire still comes with a wire gate to help cut weight.
These draws compared to the previous sets of draws that I have used in the past are a better fit for my style of climbing. I give these draws a thumbs up to anyone that can afford the $24.95 price tag.
