Nearest wireless equivalent to a Model O?

[Hades]

I love my Model O. It's the best mouse I've owned and I love how light it is. But I rarely game nowadays and am thinking of replacing my mouse and keyboard with wireless ones to clean up my desk. I have multiple wireless mice but all are heavy. So I'm looking for some suggestions for small, light, wireless mice which are good enough for casual gaming. A Logitech 305 comes to mind although I'm not sure whether I would like the shape. I prefer something similar to the Model O with the narrower middle section.

Any suggestions? Thanks.
