eek, that's not a great sensor.
Interesting you should say that - why do you feel it's not a good sensor? I've used the avago ADNS 3090 in my zowie FK for several months and I love it. It's got a great LOD too. There's rumors that the lower dpi settings has a delay but playing quake daily for 6-10 hours at 120hz/250fps with the mouse set to 1000hz produced no noticeable delay. So far it's only been rumors.
Here's about 10 well respected mice using the sensor:
Mad Catz R.A.T. 3 (halfway through 2012 production replaced sensor with avago adns 3090)
Zowie ec1/ec2 'eVo' & 'eVo CL', 'AM', 'FK'
Steelseries Kana V2
Cooler Master Storm 'Spawn', 'Alcor'
Roccat 'Kone Pure Optical'
