Need suggestions for 27"x41" one-sheet "snap" frames

For the HPF frames, I use a small piece of acid-free tape at the top center plus one metal clip at the top center to minimize rippling.

I haven't been rotating as often as I intended - the previous batch went up in July! Anyway, today I took down the frames and put in new posters. I was sure to examine the previous ones for any sign of damage or rippling. I am pleased to say that they look perfect! So for a 6 month rotation, these frames should not pose a problem. And here's a new year's promise: I will rotate every 3 months in the future!

Here's the new batch...
