The Avago9500 doesn't track well on cloth (Negative and positive acceleration) and the Ikari optical isn't known to be the greatest mouse. Both the Ikari Laser and Xai show some traces of positive acceleration on hard pads.
Christine (lmnop) owns both these mice and should be able to give a more defined answer.
Edit: Why are you considering these? You already own a majority of well known respected gaming mice.
