Gang,
Unless it's a frame-less film I would be leery of any shade intended to adhere to the canopy with static cling. The fold-up type have a flexible frame that might be unwilling to shape to the curves of the canopy, especially for the larger sizes. If that happens you might not get enough contact between the material and the window to promote adherence. Even with suction cups, a frame that isn't flexible enough to conform to the canopy shape will probably be unacceptable.
I'd stick (ha!) with the film type, or get several of the smaller fold up style with suction cup attachments.
