Hi Don,<br><br>Don't know how thick your two foils are, but my guess is that the HD is thicker / and a bit harder to get pressed down (there may also be some air space issues in addition to the extra square feet added). Thus far, I've not added any to my EDC, and have some plastic oven bags instead.<br><br>Have you tried rolling it? There was some earlier discussion regarding oven bags / foil / rolling vs. folding etc. in a past thread. <br><br>Sorry, I've forgotten which forum, search them both. Perhaps someone else has a better recollection on this.<br><br>Regards,<br>Comanche7
