I have the Livewire quickdraws, so these come with those draws. The width is great for sport climbing and they dont twist. Yes they are a little heavier than the thin dynex ones. But i would choose these over the dynex any day. I have 8 of the 12cm, 2 of the 18cm. and 2 of the 25cm. The 18cm isnt sewed at the top, so the 'biner can slide around and drop and can get weird on the harness. Other than that great dogbones.
