I have a pyramid baking sheet that’s kind of cool, but it collapses with more than a couple ounces of weight.

I use it on a silicone baking sheet (?) that is framed in ½” steel (think Barbie trampoline) that’s cool, but difficult to store.
(All my silicone has been purchased second-hand and I can find no example of this product.)

Is silicone bakeware just a silly fad, or are you really into it.
Please state if you have been into previous fads, like the ¼ ton ‘baking stone’ cake pans. :)
