What's th latest of the Logitech drivers re. how 'damaging' they are to install, when you like to have everything squeeky clean [accel fix etc etc]?

Reason I ask is I need to use those three small buttons near the mousewheel for weapon binds. AFAIK the only way to do this is to install the Logitech drivers, as software like x-Mouse Control won't work with those three small buttons.
Even if it will, the G400 will still be switching DPI every time.
I need to replace the DPI switches with keystrokes.

So, can I safely install the latest Logitech drirvers, and just make sure to uncheck the 'use setpoint implementation' thing?

Thanks.
