I've looked high and low for an ultralight 11 speed cassette but the market seems kind of bleak. The all alloy cassettes are a whole other ball game and are really a race day cassette more so than a "nice day" cassette. Here is what I've found and a comparison to the market standard, please add any options you have found along with weight (OBVIOUSLY) and price.
For me the omniracer looks like a great option but it seems like a large chunk to blow on a wear item. Looking at the weights and price of the shimano and sram options it doesn't even seem worth it to buy their top level offering vs. their second tier.

Why not just get a SRAM XG1091 cassette. Lasts for ages and not much heavier than a ti cassette. And it works.
