I'm looking to replace a few twinwall panels. Before I do, has anyone done a comparison of different brands to see which ones hold up the best? I used a few from Harbor Freight and they seemed to frost up after a few years and crack more easily. Any suggestions?

We use the corragated plastic panels, we get them from Home Depot. We drilled and screwed them in place. Our greenhouse in wood frame. We get many, many feet of snow at the upper ranch, the greenhouse has a 12X12" pitch. The panels have held up well.
