I still use a Logitech G5, pity me.

I personally use a Logitech G9x without the shells - it's the most comfortable thing i've ever used, and i've had the G5, Razer Deathadder and Microsoft Intellimouse (long ago - but that was very comfortable).
I have big hands and grip the mouse solely with my fingertips so I think that's why such a narrow mouse works so well for me - everything is easier to do.
Big hands = small mouse, try it.
