It was an article i read where it stated that the deep pow can work its way under certain bindings and cause then to come away from the board..
Ahh a magazine article. All magazine articles are thinly veiled adverts, go back and read the article again, I bet its steering you toward a pair of bindings that are advertised on the page after the article. Its a classic magazine caper.
I managed to get through a few weeks of this without my bindings being worked loose by the deep pow.
