New XTR models: What is performance?

[jdong]

Hey Mike, I see like 5 or 6 new Whistler XTR's at http://whistlergroup.com/newxtrs.asp all with the LED periscopes. Are they all based on the 690's platform, or not? What would be expected performance on these models?

EDIT: Reading the manual, the behavior sounds more like the 1793 style platform (i.e. VG-2 cloaking)

The XTR-140 / XTR-260 / XTR-330 / and XTR-500 do not share the same platform as the XTR-690 and Pro78

Their performance is similar to the Pro58.
