for me the g500 shape will be fine as its the same shell as my current mouse, and the thumb buttons apparently take a bit of a getting used to but after that they are fine
Switching back to the logitech should not have been an issue as I have always used Logitech but after the Roccat it just felt wrong, although last nights games were a little better as I made better binds, am more used to the buttons etc...
The thumb buttons on the Roccat are positioned much better and it kinda has a thumb rest so its just short little flicks to use them. The G500 I am getting more used to but I would say I will probably get a Roccat Kone again and have the G500 as standby, all in all the G500 seems like a decent mouse
Also I would say your small girly hands might be an issue with the Roccat Crunch
