Mossy: thanks!! Nope, I'm just using paper or cotton towels (changed daily until towels no longer moist). I age for two weeks typically (I've experimented the whole gamut, as you've been doing, and that seems to be the sweet spot as far as waste vs tenderness vs taste goes) and I do it so often that the bags would break the bank! Also, for me the big advantage to the bags seems to be the 'blocking of off flavors' (per dry bag site) and since I use a dedicated fridge, that hasn't been much of an issue. Next week I'll post some pics of the fridge if you like...it's my prototype, so it aint pretty, but it works like a charm...
