Double Griddle safe for glass cooktop??

[michael]

I have a Whirlpool glass cooktop oven and have read that there are many pans which can potentially crack the glass cooktop or even the ceramic heating element. Apparently this has to do with the amount of contact the pan has with the cooktop. The pan needs to be flat (no ridges on the bottom) and should not extend past the burner itself to a large extent.

I would really like to purchase a non-stick double griddle but am uneasy given what I have read on the subject. Does anyone have experience with this situation? Any particular double griddle recommendations?

Any help is much appreciated!!
