Contact Papa Smurf directly, answer his questions, and he will set you up. The price depends on layers, not material.
They vary a little bit, but most of the time the weights are real close between a DL 1.1 & a SL Poly Crinkle Taffeta.
Also depends on the suspension and any customizations made.
DB60 in Poly Crinkle Taffeta will run around 30 to 31oz.
DB68 DL in 1.0 ACU Digital will weigh approx 31.5 to 32oz.
Another advantage in my mind, is the increased safety margin of a double layer. I've seen a SL 1.1 split wide open when hung too low and accidently brushed against a rock. My guess is that a double layer might have prevented the failure (unless the damage was severe enough to snag both layers).
