I think you are losing it Snuggy. The Doval's gate opening is 25mm, which is larger than a standard oval, and the same size as the BD wiregate oval. It's also within a couple mm of the helium, and superfly, as well as larger than the JC and Neutrino.
I think that the Doval, Superfly, and Helium are among the best biners out there, and all weight in at 30-37 grams.
