First off, this isn't a topic about whether Prince Albert is good enough to want to stash a bunch (I think it is) or about whether Prince Albert will improve with age (conventional wisdom is it won't... much). This post is just about how well you folks think the current tubs will hold up over the years. Are they as solid and reliable as a tin? Is the plastic as effective a barrier? Is it realistic to think one could stash a tub and still have smokeable PA in thirty years? Or if one does want to stash a bunch, is it better to just jar it?
