Mouse Upgrade? ​Recommendat​ions?

So my Logitech MX510 has finally started to give up after three~four years of solid service.
I need an upgrade and I am open to recommendations with a few simple restrictions:
- No wireless (I hate Wireless)
- Must be light weight (my wrists are bad enough without dragging a heavy mouse around)
- Must be comfortable / ergonomic

That's it. I looked at the latest Logitech stuff but the shapes seem different and I'm not sure I'll like them.

PS - Please don't make me tell you why I hate Wireless mice. Because I will.

I've been using wireless mice for over 5 years now without any latency issues (which was only a problem like... 10 years ago).

If it's charging, get a higher-end wireless mouse (like the Mx1000 or MxRevolution) which recharge in under 2 hours.

And if it's losing it... well watch yourself

Logitech Trackman thumball. After several years of wearing out my fingers I figure I can get a couple more years out of my thumb before my right hand becomes useless

And it's small enough that you can palm it to reposition it, which is convenient.

ok so lets pretend they aren't wireless for a second but I love the microsoft notebook mice - super light, small and once I got used to that I can't go back to the larger mice. I'd try the new notebook blue lens ones. The optical ones just sucked.
