Candiru,
Diving dry, would recommend that you go with the steel 85's. And here is some more information to help you decide which version is right for you.
The two versions of the Nomad LT offer different locations for the pull dump. The Nomad LT Tech version has the pull dump located on the bottom with the inflator on the inside right and OPV located on the inside left. These can be reversed by the diver, if desired. The Nomad LT Bluewater version is for divers who need to dump gas from their wing in a vertical orientation. The primary inflator is located on the back of the wing, over the left shoulder and the OPV is located on the back of the wing, bottom left. All other features are the same on both versions. The Nomad LT comes standard with a { 12 in | 30 cm } corrugated inflation hose, a plain elbow and a { 2 in | 5 cm } crotch strap, plus two 2012 style inch ring and loop bungees w/medium snaps and chokers.
IMPORTANT: Extremely streamlined, the Nomad LT has { 22 lbs | 10 kg } of lift to carry twin aluminum 80 cylinders with a wetsuit or steel 85s when wearing a drysuit. The Nomad LT is designed to support a maximum of { 10 lb | 4 kg } of additional weight worn for trim or buoyancy purposes. When diving the Nomad LT, you must not attempt to dive with cylinders or additional weight that exceed Dive Rite recommendations.
