If you've ever check out Berrcloth's bikes, you likely saw a Mozartt chainguide. Starting at 152 grams, the Presto chainguide is right in line with the competition. It'll accommodate 32-38 tooth rings, and comes in ISCG and ISCG05 versions. The removable bash guard is 10mm thick, and the 5.5mm thick backplate is made from 7075 T651 aluminum.
