RE: essential accesories?
I've been using the shorty Doinker and found it works a lot better on an extension. 7" is much better than 4". The longer shaft seems to take up more vibration for the Doinker to absorb. Like the Q2 has a lot of vibration anyway.<img src=icon_smile_wink.gif border=0 align=middle>
Other than maybe changing to the aftermarket grip, I can't think of anything to add.
Personally, I would take off the wrist strap, but that's just me.
